If you both could reschedule without a problem, I don't see why you would ask for a discount. Asking for one is a good way to have a supbar experience, or no experience at all.Recently, I had an experience with an SP who cancelled our appointment just four hours in advance due to an emergency. The problem was that I had been travelling abroad, and we had pre-booked everything weeks ahead. I also paid the deposit using a gift card. We attempted to reschedule, and I requested a discount to compensate for the inconvenience, which SP was not happy about. We ended up with her returning my deposit.
The question is, was I right to ask for a discount?
