7-Eleven

Standard 7-​Eleven. Quite often an okay place to pick up a cup of coffee — it’s easy in, easy out.
Sometimes there are panhandlers and junkies hanging out in the parking lot, but that’s to be expected in the convenience store biz. Sometimes the local PD will show up for coffee, donuts, and to disperse said panhandlers. There’s also a Redbox outside.
The staff are usually friendly and accommodating. It’s a professional staff running the joint, and it shows — the coffee bar is clean, the hot dogs are rotating, and the shelves are stocked.
But sometimes, it’s not so well run. The smiling lady isn’t there behind the register, but an older lady (who may or may not have familial connections to the franchisee) stands there instead. She is not so friendly looking.
But you think nothing of it. You go up to pay. Then she cancels out your debit/​credit transaction and tell you it didn’t go through and demand cash. She tells you it was declined and hands you a receipt. She will demand loudly enough the whole store has heard that you’re a deadbeat who doesn’t have a few dollars to pay for some coffee.
«CASH! CASH! $ 3.70!!»
So you pay up. Even though you just got paid and you’re certain there’s money in your account, in your morning stupor you scrounge up odd change in the deepest depths of your pockets — you grab pennies from the «Take-​A-​Penny» tray. Okay, 3 dollars and change later, you pay for your coffee.
After the caffeine has set in and you check (thank technology), you verify you have plenty of money. In fact, enough to buy not just one or two cups of coffee, but HUNDREDS of cups of coffee. Possibly even ALL of the coffee! And this receipt doesn’t say «Declined» on it anywhere at all!
But what kind of degenerate goes back inside to demand justice? To go back in and possibly get into a yelling match with a little old lady? Over coffee? That’s right, nobody.
Two days later, you realize she overcharged you and that second coffee should have been free but she adjusted it on the receipt.
Forget it.
