Ooh don't get me started. I'm a dog groomer..
So.. at least once a week I get pooped on, peed on, bitten (this is usually daily) barfed on, anal gland squirted on etc. Dogs seem to like to potty AFTER you have washed and are 90% done drying them.
Owners that think I can wash, dry, and give a haircut to their hairy, smelly, wiggling wheaton terrier in a hour.
People that think their dog is the only dog I have to work on. We tell them it's 3-4 hours and they have a hissy fit. They don't seem to realise that each groomer has 3 dogs coming in at the same time.
People who want me to turn their matted-to-the-skin neglected hasn't-seen-a-groomer-in-a-year-or-two dog into a showdog.
I could go on..
