Gratuities confuse people. Somewhat predictably, the young seem to be plagued with the most widespread ignorance on tipping. Perhaps it’s just a lack of education. While just about every parent, or whatever, feels obligated to drop knowledge on topics like the birds and the bees and the importance of earning a few bucks delivering pizza, few parents deem it important to educate their offspring on social etiquette like tipping. As a result, young’ns learn this shit the hard way – that is: by being repeatedly embarrassed by colleagues or even by waiters and bartenders until they eventually grow the fuck up. They can be perplexed by sub-stellar service or why they’re ignored for long periods of time. They can even be cut off by bartenders and waiters. It’s a vicious cycle. Those folks sometimes feel antagonized and as a result – you guessed it – don’t tip well or don’t tip at all.
