Scenario:
You are young, inexperienced, working a bar when girl comes up asking for your number for their friend, who wants to take you for coffee/breakfast.
You say you are working right now, no time to swap numbers.
They ask three times, eventually you give the number.
The guy in question says at the end he has texted you.
He pays for the group of four's drinks tab and does not leave a tip.
He contacts you the next day asking you for coffee/breakfast on Tuesday.
Your parents think he is much older than you.
You only have his photo and first name so google stalking a no-go.
