I had a guy at cafe find me ok Instagram why and how?

So i was at a local cafe (well known one) withy bestie from university and there was one guy (really attractive one) who stared at me a lot... I stared too of course ! sooo he seemed interested to me... And he somehow found me 2 days later on IG and followed me FIRST!! So i texted him today after 2 days that have passed since he first followed me. He replied in 15 minutes and we chatted for a while and he told me to go to the club he works and that he will be waiting for mešŸ™‚šŸ™‚šŸ™‚šŸ™‚ hmmm what does this whole thing mean?
