People do make me laugh. It's very rare that this sort of thing happens, but every now and again you get a client who will do anything to get a bit of money off, I've been asked in the past if it will be cheaper if the client "doesnt have all that cuticle stuff done" (they meant prep!).
I had to laugh on Saturday though, it was a quiet day for me and one of the hair salon customers came through and asked if I could do her a quick manicure (file & polish). I said yes and as usual in this situation I tried to upsell her to shellac. She didnt want to pay the extra for shellac so stuck to a standard file & polish, and I did her nails for her while her colour was on her head. I used CND polish and lumos topcoat, then she went to have her colour washed off and have her hair finished, and after her hair appointment was finished she came back through to see me wih a sheepish look on her face asking if she could have shellac after all because she had smudged 4 nails while having her hair done. I was more than happy to do them for her but she had to pay for a second service which she did happily, but her "cheap" manicure turned out to be a false economy!
