I've been going to the same salon for year, but won't have some stylists again if I don't like what they did. They've started sending me a text after my visit to ask me to rate their performance. I just ignored it until one day the owner asked if I'd give them a rating and I told him the minute I'm not satisfied he'd know, because I wouldn't be back.
Actually there is one girl, who when they told me there was only her available on the day I wanted, I briefly panicked and said, Thinking about it, I need the colour doing, is M (my favourite stylist) in on Tuesday?' And went without a blow dry that day1 So yes, it is sometimes difficult to tell the truth.
