Written up for not using a tray

My restaurant is a pretty middle of the road privately owned steak house. Not fine dining but definitely a step up from longhorn or outback. Management recently decided to implement a “higher end dining experience” aka same food quality just more work for the servers. No more water pitchers, doing dishes tableside, lighting a candle for a couple’s anniversary and tray service ONLY. I’ve got a 5 table section and often have a couple more, I stay busy for hours. The other day I was flagged down and got a drink refill for SOMEONE ELSES TABLE and brought them their drink without a tray because the only one in that servers station was cracked down the middle. I got written up that night. I could’ve not taken care of a table that wasn’t mine, but I’m not running across the restaurant for a tray to deliver a water refill because another server can’t keep drinks full.
