Most all of them are annoying but rude clerks tops my list, especially younger ones who act as if you've ruined their day when you ask for assistance. Grocery clerks and baggers are the worst offenders. Once, I was trying to get the cashier or baggers attention to bag my groceries in two separate orders but they were so engrossed in conversation that I was unable. Instead I had to listen to the female cashier talk about shaving her arm pits and legs for a big party she planned to attend that night while eating crackers and slurping on a beverage.
when you do get a human on the phone, you can't understand them!!!!!!!
