It can be really tough! At my store dto ask doubles as cold bar and is responsible for helping the drive thru barista make refreshers and what not. It’s a lot to do while also trying to talk to the customer. You’ll get it eventually I wouldn’t worry. Worst case your shift will avoid putting you over there lol

I just say “let me double check on that” for their food and I warm it up while they’re waiting for me to check on it

When I first transferred to a DT, my manager and even my DM said it’s ok to say “please hold on for a second” and get help vs. screwing an order up and moving on the mistakes to the rest of crew. I knew the drinks but mostly marked cups up until then, and never needed to add modifiers unless they needed to be charged for it. So finding ALL the buttons took time, so add that to gathering food, RTD, prepping orders, making sure each drink was cleaned off from a messy bar person, took a TON of time to get down pat. I could eventually do it all in my sleep, but I’d be so nervous. So take your time and don’t be afraid to ask for a quick pause to ask for help, it’ll take less time overall than letting a mistake go through.

That’s how our store works too! You’ll have to try and get a routine down! I gather the food as they’re ordering it and get it in the oven while taking orders
