So I have an appointment at the hairdresseres next week, a trim and some colour, will take 2 hours plus. AIBU to take my laptop with me and get some work done? I really don't want to waste 2 hours reading trashy magazines or having a forced conversation about the weather/where I'm going on holiday/how long I have been living in the area etc. Would it be different if I was in there for 30 min, but 2 hours.... What's the etiquette?
