Bar billiards can be a different situation than playing in a dedicated pool hall. When shooting pool in a sports bar, it’s important to follow some basic etiquette to ensure an enjoyable experience for everyone.

DO’s:

1. Introduce yourself to the other players if you don’t know them
2. Ask for permission to join a game if someone else is playing
3. Respect the rules of the game and play fair
4. Offer to pay for your own games and drinks
5. Offer to rack the balls if it’s your turn
6. Clean up after yourself and return cues and chalk to their proper place.

DON’T’s:

1. Jump shots (shooting the ball without hitting the rails) unless agreed upon by all players
2. Touch other players’ cues or equipment without permission
3. Play rough or deliberately disturb other players
4. Leave your drink near the table, spills can damage the felt
5. Be too noisy or disruptive, respect the other patrons and their viewing experience.
   

Bar billiards quick tip:

This is how to choose a stick at a sports bar. https://billiardsguru.com/buying-a-pool-stick/
When selecting a pool stick off the wall, first make sure it’s straight. Roll it on the table and make sure it doesn’t wobble. Check the tip and make sure it’s not flat or crooked. It should be round and positioned in the middle. Make sure the ferrule is not cracked (the part right under the tip).

Find a weight that’s comfortable. Light to middle weight cues make it easier to control your power but a heavy stick might feel better to a strong person that puts a little extra mustard on it.
Sports bars usually have a range like 18 to 22 oz but they go higher and lower. Just don’t expect pristine sticks when it comes to bar billiards. They get abused just by the sheer number of users and can get expensive for sports bars.
People eventually buy their own cue for a more custom fit. As you improve, having your own cue will help you be more consistent. https://billiards.colostate.edu/faq/cue/selecting/
