Stop in for a cup of coffee

The guy asked for my phone number as they always do because they have your info to send you promotional material. So I gave the number as I always do. This time the guy says "I should remember that number to take you to dinner" as he winks. I must have looked surprised because he tried to play it off as a joke. Then I said, are you serious. Then he said, well I don't want to offend you but I would call you to discuss how you're going to use these tools. By then I got the idea he is clowning around, so I said "go ahead"

He hasn't called yet but he took an extra 5% off the whole bill.
