I've been told (mainly by my mother and my girlfriend) that having a meal with me can be a TRYING experience. Why? Because enjoying a meal out with friends is one of my favorite things to do, and when people THAT I AM GIVING MY MONEY TO in order to do this fumble through and fuck everything up, I get pissy about it.
Shitty service or shitty food, of course, are the most egregious of errors. How can you enjoy your meal or your conversation if you're spending time desperately trying to make eye contact with your clueless waiter in order to ask for another drink or a condiment or whatever the fuck else you need in order to enjoy the meal you paid for? And nobody's happy when your order shows up the wrong way because everyone just has to sit there waiting for your order to be corrected for the sake of being polite, and then you have to wave your hands in the air saying, "EAT EAT EAT" and then they do and your meal inevitably shows up after everyone's done and it's just honestly the worst. These are the verbal complaint-worthy things.
Then, there are the more bougie things that most people wouldn't notice and you would look ridiculous if you brought them up. Like, for instance, being served a lovely bread basket with an ice cold brick of butter. What are you supposed to do with that shit?
Thankfully, the folks behind the Butter Up Knife ($12) solved my white people problems, by creating a tool that allows you to conquer bricks of cold butter by gently grating it into spreadable pieces. You probably shouldn't bring this to restaurants, though, unless you want to look like more of an asshole than I do.
