<P> Products may be out stock in relatively small brick and mortar retail stores and due to limited space in small business retail stores, these establishments may only be able to carry a few types of each product . Online shops are able to have a huge amount of stock in numerous large warehouses (e.g., Amazon.com has warehouses in numerous locations from which it ships its products) which it can quickly ship out . An online store may be able to order up products from a large number of geographically dispersed warehouses, even warehouses owned and operated by third parties (e.g., smaller companies), which are connected to the large company via the Internet . </P> <P> Queues (lineups and waiting rooms) are part and parcel of B&M retail businesses, due to physical constraints and the limitations on how many staff the business can afford to hire . A physical store may only have a few salespeople to serve customers, so many customers may have to wait in line during the busiest hours . To lessen the stress of waiting, some B&M stores provide big - screen TVs with cable TV, free coffee and newspapers; while these niceties improve the customer experience, they add to the costs of operating a B&M establishment . On the other hand, an online virtual store in which customers select their own purchases in a virtual "shopping cart" and pay for them using e-commerce approaches may be able to serve thousands of customers at the same time . </P> <P> Beginning in the 1990s and early 2000s, many governments in industrialized countries began to offer e-government services to citizens . Online government services are offered by a range of government departments and agencies, ranging from departments of motor vehicles (online car registration), police (paying speeding tickets online), city services (paying parking tickets online or requesting that a pothole be filled) and social services (registering for social assistance or unemployment insurance) and tax departments (paying a tax bill or submitting a tax return online). Many governments use e-services to provide online information to citizens (e.g., "help" guides, Frequently Asked Question lists, manuals for government program applicants, etc .), thus saving on the need for call centers where citizens can call to ask questions or physical service locations where citizens can come in person to ask about government forms or services . </P> <P> These online government services aim at two goals: reducing costs to governments and improving client service . By offering these services and information online, governments save money, because they do not have to offer as many bricks and mortar client service centers where citizens can come and fill in these forms and pay government bills . Governments offering e-services can also operate with less civil servants and thus less salary and benefits costs, as the citizens using online services are generally doing all of the administrative tasks (e.g., downloading a form, filling in a form, looking up guidance in an online "help" manual, paying fees) themselves using their home computer . E-government services also improve service for citizens who have access to a computer, Internet and an online payment method (e.g., a credit card or PayPal), because these citizens are not limited by the 9 am - 5 pm or 8 am - 4 pm business hours of most physical government offices, and citizens do not have to incur the costs of transportation (e.g., bus tickets, gas, parking, etc .) associated with going to a bricks and mortar location . Nevertheless, government e-services do not help all citizens, due to the digital divide; citizens who are in poverty, who are homeless or who live in rural or remote regions may not have access to high speed Internet . These citizens, as well as those who are not comfortable with computers or those who do not understand how to use them, which in practice means elderly people, are not able to benefit from e-services . </P>
