NO PROBLEM..............what in the hell does that mean. It seems to be a replacement words for your welcome. When I tell someone thank you for them doing their job then they tell me "no problem" I feel like asking them if doing their job is normally a problem but this time it was no problem.
I'm an old grouchy fatherless child and I could go on and on about pet peeves.
OK just one more since you asked.
This is also a bathroom peeve. When some one goes into the mens room and decides to turn the stall and toilet into their urnial, without lifting the seat. Then they commence to pee on the seat, the floor and probably thier pant leg and shoes. Then the low life leaves without flushing the toilet nor does he wash his hands.
