You often visited the same club, tasting different alcoholic drinks, as well as enjoying a party. However, you noticed that the same bartender served you all the time, although there were others..He behaved a little strange, looked at you all the time, blushed and was very embarrassed.

When you once again ordered a drink for yourself, then when it was brought, you noticed a piece of paper.. What is this? Phone number and name of that bartender?
