The best advice I can give is tone. I think when it’s busy like it is (I also work a busy drive thru during peak) the way you say something is much more important than what you say. Also lots of “thank you”.

Address the action, not the person. Like it’s not ‘X didn’t make back up whips!’. Address it as ‘backup whips were not done and we were low.’ Or one thing I use to ask for things is making it about the business and not something YOU want done. Like I’d tell the crew before me to leave me with certain backups because with block scheduling, it’s about servicing the customers right away when my team clock in.

this is something that i’ve been working on for a long time because i inherited my dad’s short tone and temper, and i found it really helpful to just be honest about it. “hey, i’m sorry if i came across as snappy, that wasn’t my intention and i’m working on the way that i speak, if you could please let me know in the future if i come off sounding short or rude i would really love to be held accountable.” i have a habit of coming off condescending, and i’ve had to have that conversation with many people i’ve managed, because that’s never my intention but sometimes i speak that way without realizing it. it also lets people know you’re aware and working on bettering yourself.
