<human>: I was at Menards and at the checkout the cashier had OCD (according to my wife who has worked as a mental health professional). The cashier was rearranging items we we put on the counter before she scanned them. There was a can of sparkling water with a price tag that didn't ring up. The cashier tried about 10 or more times to enter the code from the label on the can. I said "forget it, I don't want it" and then she turned on her light to get a manager. I said, "forget it," again. She heard me but refused to listen at first. So I had to say again "Mam, I don't want that." Knowing that she could have easily just have done an override and manually typed in the price this really bothered me (I've worked as a cashier before). That wasn't all of the weird things she did. When I handed her a $100 bill she asked if I had something smaller. I said "No." She acted like she could't accept my money. I said "I'm sure you can get change if you need it." She didn't need it, she had the change in her drawer, a few twenties, etc. Also, prior to even checking out, this cashier was asking us, if we were going to check out, we were still looking at items. I should have never went to her counter. I will never go to her again, even if she's the only cashier in the store, I'll just drop my shit and walk out. I'm sure some of you may say that I'm over reacting about this, but the whole experience bugged the shit out of me. My wife just laughed. She said, she had clients that had OCD and it didn't bother her at all. I almost felt like going to a manager and talking to him/her about this employee. I won't, I think this person should probably be used elsewhere in the store, maybe stocking shelves (I'm sure they would be really good at that).

Condense the text into a few key points
<bot>: Annoying cashier tried to enter price of item 10-15 times, wouldn't accept money at first, other issues.
