Yesterday I witnessed 2 customers that said " I have to go to the bank and get the cash,or, i gotta go to an ATM and will be back". This has to happen all the time. Once a customer leaves the store, that customer has the chance to not come back. Get the Money now. Don't give them the chance to leave without buying. That's just not smart business. On the other hand, people pack their store and shell out cash and cards all day long (when they are open) so the are obviously doing something right. I'm a noob and my wallet has puked all over their store. But they still need to change the sign and price tags.
