Some of the things I thought are - 

Asking the same person the same question over and over again - 
In video games, most of the time you are able to talk to the same person as many times as you want. Imagine if you asked your teacher “What are we doing today?” 50 times in front of the class!

Looting people
Taking dead people’s items from their bodies is generally perceived as, to put it lightly, slightly rude in real life, but it’s totally okay in gaming.

Pausing
In the middle of an intense fight with your arch enemy
“Wait… sorry….. need to look at my inventory…. haha…… just wait right there…"
Police giving up on chases
Police cars, sirens blazing, chasing after criminals. The criminal van takes several sharp turns. 
"Oh.. I think we lost them, Officer"
"Ah... It's cool btw did you know there's a COOL movie releasing today? Let's watch it!"

XD These are all I could think up of. 
YOUR TURN.
