This was one of the most surreal moments I've had in quite a while... Went to McD's for some lunch. Rolled up and ordered a meal that rung up to about $6.40-ish. Gave the cashier at the window a $20. I was promptly given $3.60-ish cents in change. After dropping the coin in my coin holder I noticed all I was given in bills were three ones. I handed the three ones back, and told the guy I'd given him a $20....dead silence....and a confused look. The cashier started pawing through the bills in the register...then turned to the manager next to him to ask what to do. They decided to count the drawer down to confirm I wasn't trying to rip them off. After about 5 minutes of waiting, the manager came back out with the food, the receipt, and two fives. He gave me the food and then told me they'd counted the drawer and that it was only over by $10. The precise amount I'd been shorted, I reminded him. He then asked if I'd given the cashier the three ones back (he was standing by the chashier at the time and actually saw me do that). I told him I'd given the three ones back. He then restated that the drawer was only over by $10, then handed me one of the fives he had in his hand to make me whole again. This guy, the manager, was just as confused by the huge scale of the numbers racing around this conversation as the cashier was. When I told him the other $5 was owed to me as well, he simply stared at it, and muttered AGAIN "but...the drawer was only over by $10". "That's my $10 you were over" I said once more. He then reluctantly handed over the other five as if he just knew I was ripping him off, but not before saying "but...this all still leaves you $3 short". I agreed...and asked if the cashier had counted the $3 I returned with the drawer cash or if he'd just set it aside to focus on what was in the drawer and in question. I think his head was about to pop at this point, and so was mine. I told him $3 wasn't worth the trouble of teaching him remedial mathematics...they could keep it. Seriously.....a store full of employees and they can't figure THIS out?
