I gave a guy my number and he hasn't reached out yet, should I stop waiting for a text?

I went out for drinks with a friend a few days ago, and I thought the waiter was cute, we chatted for a bit and at the end of the night I gave him my number. It's been 3 days and he has not reached out yet. Should I keep waiting or is it a lost case?
