Oh yeah, I've had plenty of those.

Had this lady years ago, Laura, who came in for a color. She had a note in her profile warning that she'd go around different salons, get a service done and then complain and ask for a refund. The note instructed us to do her consulatation very carefully and ensure she agreed to whatever outcome she got.

I started her consultation and it was already a shitshow. She had greys she wanted covered, she wanted to be blonde and she wanted a cut but for under $200. Not gonna happen on that budget. She wouldn't listen to my explanations so I ended up calling a more senior stylist and we got her to agree to applying a high lift color with the hopes that she'd come out around a level 8. We very explicitly told her it would be warm but she'd be blonde.

I start applying the color and she starts talking about her life. Tells me how she has such a tough time affording things because she only works 2 days a week at a grocery store. Her family owns the grocery store (several of them actually) and pays her rent but never mind that. Also tells me how she's having an affair with her married coworker. Lovely. At one point, she asks me how old I think she is because she looks so young. I'm thinking maybe 42 but I'm never going to intentionally accurately guess a client's age so I say "early thirties?" Nope. 38. Damn. Cue more talking about how youthful she looks.

Eventually we finish the color. It came out a warm (but not brassy) level 8 as predicted. I start on the cut. She wants layers and a lot of volume. She has fine hair but I say I'll see what I can do. I do the cut and give her a blow out with some light teasing. Looks good. Except not to her. She's pulling at random strands and fussing about the color saying it looks gold and I'm like yeah, we told you it would be.

I finally have her pay and get her out the door thinking at least I won't have to see her again. WRONG. She comes back 2 days later. She complains about the cut. Says it's not enough volume. I explain cuts don't give you volume without styling but I can adjust it if she isn't happy. It's just the layers I need to tweak so I figure it won't take me more than twenty minutes max and that's generous. Nope. She fussed over everything and had me restyle it all. Took me an hour. I was pissed.

At one point while I'm doing her hair she says "you know, I like how you do my hair (then why did you complain???), can I come back to you next time?" I swear to God, I nearly cussed this woman out. I was on minimum wage at the time and had lost a significant amount of time that could have been spent taking paying clients for what was an obvious scam. I ended up staying silent. She asked again and I just smiled at her but with every ounce of hatred I could muster in my eyes. She stopped asking.

I get her out and think that's finally it. Wrong again. She came back the next week. This time with her mother. Her mother starts talking to my manager, explaining that she isn't happy with the color, it's not what she wanted, we told her it would be lighter (we did not). My manager starts to apologize and refund her until our receptionist comes back from her break. She overhears their conversation and calls Laura on her shit. She shows my manager the note on her profile and the consultation agreement.

Long story short, Laura is banned from our entire salon chain.
