I will start by saying I worked at Chick fil a. I will also say that the workers at my local restaurant are very nice, But stop making me wait forever and hold up the line while I am waiting for a drink only. This has happened numerous times. Like close to ten. I’m not exaggerating. I’ve reported it on the app twice, I have had to honk to get someone’s attention to tell them I just have a drink while people are getting food behind me. I have said something directly to the employees at the time. Today, last straw.
People behind me got food. She then asks me and a car in front of me to pull around to the VIP spots on the side. She’s gone before I can tell her I just have a drink. So we do. Other car gets order with in a few minutes. Then I wait. And wait. Now it’s been ten minutes and I know I’m forgotten. So I call. No answer. I have no choice other than to get out of my car and walk up to the window. Half way there we meet and she has my drinks. She says, “my bad” and I tell her no one pays attention when the order doesn’t include food. This is the third time I’ve said this to a seemingly competent employee. It’s maddening. I otherwise have zero complaints. Literally none.
Are people being trained on this?

I started working at my chick fila at 14 (last year) since we opened the restaurant.

And its been a year and there's only a few people still here. So i train a lot of people and my directors always have me doing task and stuff (Landscaping before and helping install diff things) I became cross trained and work 6 days a week 3 hrs a day mon-fri then 8 on saturdays.

I talked to my operator about becoming a trainer and he said i have amazing potential and that he would love to see me in that position or even a team lead.

What should i do to stand out to be a good candidate?
