I booked a luxury facial for 1 hour and 15 minutes which started slightly late and finished early. Overall, I was there for only very slightly over an hour. At the end I queried this when she tried to charge me the higher price. To be fair, she did let me have it for the cheaper price but I still left the salon feeling like a cheapskate even though surely it's not my fault if it finished early?
Was I unreasonable to query it or would you just have left it?
