Don't ever feel bad for ensuring you won't die for a $5 cup of coffee. I work at a licensed location and previously worked for a corporate store. Even if the baristas find it annoying to have to track down their shift manager to make your drink, that's your store's specific policy and they clearly have it in place for a reason. I am MORE than happy to even go to the kitchen and flat-out wash (instead of just rinsing) a piece of cross-contaminated equipment, interrupting my drink sequence flow, in the middle of peak, to make damned sure that a customer's drink is as allergen-free as I can make it if that's what they need. Your safety is a thousand times more important than my inconvenience. That said, it is also your responsibility to inform food service workers of your allergy. (Not saying you don't know that, but there have definitely been times where--as allergen-conscious as I try to be!--I've gotten careless. If you ever have doubts about whether your drink/food was made the way you ordered it, please PLEASE double-check with your barista/server/etc). We have guests at our store who will have a medical emergency if they have too much caffeine, so we always make sure to very deliberately keep an eye on the espresso shots being pulled for their drinks. We have people with preferences for non-dairy milks and whether it's because they like the taste or because of an allergy, we do our very best to make their order correctly. I've been asked my own recommendation for non-dairy options by guests looking to try something new or maybe even because they have a sudden change in their dietary needs/restrictions. As long as you're clear about communicating what you need and you're nice about it, I could not care less what I have to do to ensure that you won't have a a medical emergency because of an easily preventable mistake. It is NEVER annoying to me to provide you a safely-consumable Starbucks drink.
