Being a server is really hard work. Despite being perpetually underpaid and underappreciated, being a waiter is no easy gig. Just think about how many times you've left a restaurant after receiving great service — that's all because of one person who takes their job seriously and prioritizing their customers.
However, if you're going to be disrespectful and rude to your servers, you have to expect that there will be some sort of repercussion for your behavior.
