Do y'all get service charge waived off?

How about an option stating Depends - on the quality of service provided I feel this is the most important factor influencing my decision

Yea, directly tip the guy who served me. They don’t allow at some places claiming they share it with all the guys, so yea those places cant do anything
Is service charge actually shared among all the wait staff and workers or the establishment pockets tho?
They usually waive it off if you ask so I don't think the wait staff is getting the share?

You missed the one right question. Depends - how good the service is. For ex. in BLR most normal restaurants clubs and breweries have absolute ass service even on days with less footfall.

these charges can be waived off ?? I have never tried that.

You missed a key option, "depends how good the food and service is"
