A Phrase A Day: Put it on my tab

Hi everyone!
I'm launching my show! It's called A Phrase A Day.
The goal is to teach you colloquial English. We're going to learn lots of English phrases, using little parts of different movies. Each video is no longer than 1 minute, so your learning process will be as quick as a whip.
Today's phrase is right here:
"Put it on my tab" - Запиши на мой счет.
This one means that someone's going to pay full amount later, e.g. at the end of the evening.
Examples:
1) Throw away every French fry in the place, and put it on my tab.
2) Well, tell the inspector he can put it on my tab.
Use it wisely! See you!
