San Francisco, California
Vlry easy to locate on arrival, and we were proccessed very efficiently, with little time left waiting.Driver a little erratic on road, ducking and diving across lanes at speed. he dropped us off and put his hand out and said 'TIP??, you give me tip!!!!!!!!!! As we are not used to tip procedures, caught us off guard, we were left embarrassed....seems to be the expectation, not option!
