NO Corn Salsa

A Chipotle is a block away from where I work, so naturally I frequent it often. Every time I go in, as they're making my Burrito(or tacos) they ask what toppings I would like. As always, I as for everything BUT Corn Salsa. What do I get? Corn Salsa and nothing else...

I know what you're thinking, and yes, I've tried asking many different ways but no dice. So, I'll have to resort to wasting everyone's time by asking for each topping one by one.

What's so hard about making sure the people directly involved with the customer can communicate in English?
