The water thing kills me. Once made myself a cup of water on bar, kept way off in the corner, no way it would ever be mistaken for a customers drink. Got yelled at by my shift and she brought the water all the way to the back. About an hour later I walk to the back to take a sip of water and the same shift screamed at me for abandoning my post (there were no mobile tickets and no one in DT). Ridiculous, I get thirsty working bar, either cover me for the 30 seconds it takes for me to sip my water or let me have my water by the bar, I’m human.

For the shoes thing: go to a running store and get fitted. Make sure to try them on, you should feel slightly uncomfortable with the arches pushing against your feet. Not painful, just oddly uncomfy. Then get those little pedicure kits from the dollar tree and pop those little weird toe spreaders on while watching tv. It'll help move your foot bones back into their straight lines by relaxing those muscles and tendons.

I used to hobble when getting up in the morning.

Maybe you just don’t feel comfortable doing this because you don’t want to leave your partners hanging and I understand but people at my store leave when it’s time for them to get off and I think you should do the same, especially considering you’re situation.
