My idea is the next one:
There is a party and the guests want to order a pizza, so they call to the closer pizza restaurant but it's impossible to talk to the operator because it's very loud, then a guest pass them a cellphone or a laptop and he show them meseroexpress.com and then they can search the restaurant they were trying to order and they see the menu to order easily by Internet, adding each pizza to the car and paying on the website (Español)
