We might have done this before, but I thought it would be interesting. Since I am an old person, I guess a lot, lol.
1.No hook in the ladies room to hang my purse on, where I have to sling it over my shoulder or put it "yuk" on the floor, sometimes there is not back on the toilet, just the flusher.
2. People talking about unimportant stuff on their phones,i.e. telling the listener about what shes making for dinner that night.
3. Young folks blasting the car radio/stereo where you could hear it,possibly couple of states away.
4. People who don't control 'unruly' children in public
5. Folks who blow their noses after dinner when dining out, and you have just started yours, and put the dirty napkin on their dinner plate
just a few of my 'petpeeves' looking for yours....thanks, LadyJay
