Get your RMs info and contact them directly. Tell them about how negative of an experience you had today BECAUSE of your DM and how she was a detriment to your partner experience today. Specifically how your SM and RM were being positive and helpful while your DM was not.

Hopefully the regional manager gets on your DM's case. Our DM noticed we were struggling and asked what was up. And I told them two people still hasn't come in for their shifts. The DM came and did CS. Brewed coffees, changed a trash while the SM called the partners that were late, then helped out bar. Though or DM started their career at Starbucks as a Barista.

It's probably too late now, but my FAVORITE thing is to redirect angry customers to my DM. Like "sorry, we wanted to help the wait by limiting orders to just in store, but unfortunately MY DM OVER THERE said no. You can talk to him about that!"

Ours has gotten back there and it's been a help. They did work their way up from being a barista, so that could be a difference.
