Far be it from me to tell anyone how to run their business, but I know that as a consumer, I am sometimes asked to pay in advance, for example at gas stations or at McDonald's drive-thru.  I don't see a difference.

Of course, one should exercise some discretion.  If we're only talking one or two orders, I may go out on a limb, but three, four or more is pushing it.  If they don't want to pay up front, I tell them no thanks and best of luck, no harm, no foul.  I always welcome new customers, but I refuse beg for work.  I'm able to be more selective because my clientele is the best in the business.  They are extremely loyal and always keep me plenty busy.
