Whatever anyone says during a business transaction can be thrown right in the trash, it's useless. I don't even earn tips and I know enough not to complain about my job to clients. When speaking to clients and customers you're going to try to be positive, doubly so for customer service.

Either way, everyone I know who drives for Uber is very financially illiterate and believes gas in their only expense. So the amount of money that they think they are earning might not match reality - that's the case with the people I personally know at least.
