A bartender gave me multiple drinks for free and I gave him my number. How long do I wait to chalk it up that he won’t text or call?

When I sat he gave me multiple I mean he didn’t charge me for over $100 in drinks. I’m not a huge drinker so don’t go out a ton but seemed a little odd that he wouldn’t charge me for all of those.
