Renee, yes there are bad groomers out there. In fact I've fired a couple in my day. But there are bad EVERYTHING out there nomatter the profession. The thing is, get to know your groomer don't be suspicious of everything, things you don't know about or understand just ask questions. If you don't feel in your gut you can trust your groomer than find another one. When you find the one that makes you feel the most comfortable by all means tip her!!! LOL just kidding, actually a good tip is saing "Thank you, you did a nice job he/she looks terrific!" that's tip enough for me. But anyway you will find that the majority of us are good people who love animals and, yes even those that have part-time jobs driving busses or whatever.
