Went and got my hair done at the local hairdressers, just a dye and trim. The card machine was broken, so they told me to come back with the cash the next day.
Got home and was looking at my hair, and noticed it was patchy. I had it dyed from dark to a coppery colour. I'm really tempted to tell them I don't want to pay full price, as it's quite patchy. AIBU? In fairness, I definitely won't be back to get my hair done with them again, ever.
