Learning the retail business

So far I've seen four customers come in trying to buy $200 visa gift cards (and usually some expensive item like a laserprinter at the same time) with checks. Every time the little pop up screen appears telling to phone for a verification. Every time they say no.

Quite frankly every time I've pretty much known as soon as I saw them take the checkbook out that it was going to be a no-go. 90% of the time checks go in without a problem, but if that pop up window appears it means you been writing rubber somewhere else.
