The Slugfall Cantina on Mek-Sha is unique as it is the only one with Bouncer NPC’s that do their job.
If you stand ontop any of the Holo-Tables with holographic Dancer NPCs, a Bouncer will pull you off with a rope and tell you to cut it out.
You may notice a debuff appear on your character for 30 seconds, each time you stand on a Holo-Table again before the buff runs out it will add another stack, counting up to 4.

Each time the numbers increase, the Bouncers will get angrier and angrier with you. Once you reach 4 stacks the Bouncer will knock you unconscious and throw you outside of the Mek-Sha cantina, with your character waking up a few seconds later, stunned on the ground and the Bouncer telling you to keep out.

If you go back inside and jump on the tables immediately, nothing will happen and they will continue to pull you off forever. However if you let all 4 stacks of the buff run out after 30 seconds, it will begin counting from 1 again and you can get thrown out over and over.
