I Hate People Who don't Pay it in Cash

Cash and Carry (doc: geroboknakroboh.blogspot.com)

 As a retail business owner, I sell some varieties of the consumers need. Of course I am expecting people to pay it in cash rather than pay it later, because my fund is just limited. So, I don't like the customers who didn't pay it in advance. I try to eliminate from now on and will never take it. I need to strict to the rule I have made. Otherwise people will be easy to fool me. That's not right  and will not happen anymore.

All has to be paid in cash. Yes, Cash and Carry. It means no cash, nothing can't be carried out. I can't wait to get the money it back out and then will stop doing it. It hurts my feeling and making me upset to them. How come they use it as a habit buying with no money?. I really hate this kind of habit. Moreover I am not a banker. So for this reason I will not reply all the messages come in and no credit allow it. Hope they understand my situation. Cash and Carry is my policy. No Credit for ever. Thanks.
