I can understand not blatantly asking customers for a tip, as some other transportation and service companies do, but why does Uber go out of its way to tell customers not to tip? As a service job, it is accepted that some customers may give a tip and they can decide to do so themselves. By advertising that no tip is necessary, it is basically stopping customers who would normally tip from doing so, which I feel is unfair because Uber does not provide any bonuses or extra compensation. I once went to a non-gratuity salon and put the tip I was going to give the person back in my pocket because they told me not to tip. This is the same thing.
