Any resources on correct drinking protocol for certain drinks?

I recently embarrassed myself at a bar with friends by squeezing my lime into my tequila shot. I had never had tequila before, but 100% of the time in the past, if I was served a drink with a citrus fruit slice, it was meant to be either squeezed or totally put into the drink. I wasn’t aware that you’re supposed to bite the lime after drinking tequila. Apparently I’m the only one who didn’t know this, because everyone who I tell about this acts like it’s common knowledge.

Are there any other drinks with unusual/distinct methods of consumption like this? Is there a guide or any resource I can look at to be more prepared at a bar? I don’t have much experience with drinking but I want to look like I at least know what I’m doing.
