The problem is that they aren’t legally required to do that. They should be. And thus tipping would not be as necessary. Of course some servers like tipping, and I get that, but if they were paid effectively the same as a proper salary then they wouldn’t have to hope for a busy night or hope people are generous on any given night. Whether any given server likes the notion of tipping, it is a stress they have to endure — and in my opinion, an unnecessary stress.
but if the employer is not willing to do that, are the costumers morally obliged?
