I'm going to take an opposing view to most comments here: 1. Yes, you should tip at a coffee shop/food truck/counter restaurant if the staff are slammed–especially so if you're the reason they are slammed. These employees are likely underpaid and the people at Glass, Lewis & Co probably make 5-10x what this dude makes. I don't think a 15-20% tip is necessary, but some type of tip is appropriate IMO. 2. While the tweet was a mistake (he admitted so in a round-about way), I don't think he should have been fired and Glass Lewis & Co's overreaction just backs up my opinion (established by them not tipping) that they're jerks. 3. This guy used the same Internet to "shame" a customer that people use to give 1-star Yelp reviews for the most ridiculous reasons. The door swings both ways. For all we know, GLC's $170 caused bad reviews by other customers who had to wait. I hate it when customers belittle my customer service employees in help tickets and I will jump in and tell them to back off at times. Granted, none of my employees have tweeted about a jerk customer–but even if they did, I wouldn't fire them (I would definitely apologize and try to make it right).
