I had pretty much the same experience with her. Booked for 45mins and only just got naked and to the bed with 12mins left on the clock. Clearly it's her way of forcing an extension and only providing rushed/minimal FS, or taking payment without providing any FS at all.
Although, she does have bubbly/cute personality which I did enjoy. But ofcourse I didn't pay to spend time to just talk. Having said that, I feel she would be more suited for escort/psuedo-date work rather than a shop worker.
