It's normal to have customers come in with coupons. Anywhere from cigarettes to condoms (yes, condoms), people bring in their coupons to use in our store.
What they don't know, is that I'm the coupon police.
I obsessively check coupons to make sure they are real, and also to make sure they aren't expired. Many times they are expired.
Some people really don't know their coupons are expired, but most of them do know. And they try to use them in my store.
I can always tell when someone knows. It's all in their reaction when I tell them the coupon is expired.
The ones that had no idea will be like 'It is? Oh, I'm so sorry.'
But the customers that know their coupon is expired and are using it to try and get away with something will automatically, without any thought, say something like 'Oh, well throw it away then.' They will not question at all about their coupon not being usable. They usually won't even look up at me when they are saying this. Like they are afraid to look me in the eye.
So that's how I know that those people are lying. But, at least they don't argue with me like some customer did one time.
Me: I'm sorry, sir, this coupon is expired.
Customer: What are you talking about? What's expired?
Me: Your coupon.
Customer: Coupons don't expire. Give me my $1 off these smokes.
Me: Yes they do sir. (I show him the coupon.)
Customer: That's bullshit. It's just a piece of paper. Scratch the expiration date off and no one will know.
Me: Sorry, won't work.
Customer: Fine, I'll just go somewhere else and use it.
That's when he ripped the coupon out of my hand, left his stuff on the counter and walked out. Fuckface.
My point? Please check your coupon's expiration date before handing them over to your friendly cashier. It's not our fault if you're caught being an idiot.
