Earlier quoted context omitted.
Yeah, this is the problem when an establishment bucks the local trend and becomes a "no-tip restaurant" exception. Go to a country where hospitality staff are paid a 'fair' amount and customers aren't expected to tip and this problem goes away.
Indeed this problem goes away. A new one pops up though: mediocre service, such as having to ask many times for refilling the tap water bottle or get condiments, and struggling to get the waiter's attention in general.
I'm not sure why you don't think that tips are the only incentive for businesses to have good customer service. Places with poor waitstaff drive customers away, and that restaurant goes out of business or the waiter's fired.
