I have many, but for the moment I'm just going to post the ones related to customers at work.

People who walk in for their appointment and you go to check them in and they get a cell phone call...so instead of ignoring it, or answering it and saying they'll call back...they stand there and talk for 5 minutes while I have to wait for them. Usually I'm really busy so its really frustrating.

People who are late for appointments and don't even say they are sorry. I've had people walk in more than an hour late and don't even apologize or ask if we can still groom their dog. They EXPECT us to, and would be pissed if we said no. Um ok so our time doesn't matter?

People who let their kids run wild in the store and the salon. I've had kids barking and howling at dogs, climbing on the railing, etc. and parents that don't even look over! I also HATE it when parents have their kids call to make an appointment. Every 2 seconds they are having to make me hold while they go and ask their mom or dad....why can't the parents just call?

Not related to work but it drives me crazy when people say "nucular" instead of "nuclear" and "simular" instead of "similar." Double negatives annoy me too, though I know I slip and say them as well. Example: "I didn't do nothing!" What you really mean is that you didn't do anything, but when you say you "didn't do nothing" that mean's you did something. Ok that didn't even make sense lol.
