well let's agree to disagree.
The OP paid extra for the extra time. He tipped nearly 45%. The service was simply adequate, but not above and beyond the call of duty. Guys often pay too much for less service and then the providers start to expect it. When a provider clearly goes out of their way to wow the customer, most, not every, but most mongers recognize it and reward it accordingly. If the OP reported some, or even all her clothes came off and he caressed her sweater kittens and she made him feel like a king then sure, drain the bank account!
But the fact is, his overall assessment of the experience was a NO recommendation. Who feels generous with the gratuity when the service was sub par?
