A regular always buys three shots every friday night then leaves.

The bartender one day gets very curious after a couple months and finally decides to ask the man:

BT: "Why do you always order three shots first thing, drink them, then leave once done?"

Reg: "Well, my brothers and I became separated once I moved here for business. We use to drink together all the time every Friday night to start our weekends off. So, before moving here, the three of us agreed to always have three shots each wherever we move to. This way, we can always feel like we're together."

The bartender found this to be very thoughtful and smiled. A couple weeks go by and the one night the regular purchases only two shots. The bartender immediately becomes upset and walks over to the man:

BT: "Hey, I just wanted to say, I am sorry for your loss. I know the three of you were very close and I hope you're alright."

Reg: "What are you talking about?"

BT: "Hmm? You told me you always got three shots so you and your two brothers always felt like you were together wherever you were. So when I saw you only get two shots and drink, I thought one of your brothers passed."

Reg: "Oh, no no no, my brothers are fine! I just decided to quit drinking!"
