It's not as blatant as it sounds..but I think this one is worth mentioning. There's been a few times where I have had appointments that were too easy and short...
Now, I go by the hour. However, The websites I'm on do not give the option to provide a 30 minute rate. However, its been times I've gone to bookings and they only stayed about 15-20 minutes and was given my rate. There was 2 particular bookings I recall that were so easy and short, that I almost felt like giving them back a few tenners.
Would that have been ok, or unnecessary?
