I have become progressively frustrated with Killer Burger when I order more than 2 burgers. They never label the burgers, so when my office of 16 people all order for lunch, we have to go rooting around in everyone's food to determine whos is whos, and we have gotten it wrong.
This last time was the tipping point for me. We have one person who is gluten free and needs a GF bun. That person and another person ordered the exact same burger. One with a GF bun, the other with a regular bun. The GF bun was not labeled. They had to rip a piece of the bun off and taste it to tell the difference.
The names of burgers (or even better, a person) should be written on the to go boxes. We used to order from here quite often, but because of this, we rarely do now. They used to label the burgers, but for whatever reason, now they do not.
We've also had issues with someone ordering the burger where the main ingredient was BBQ sauce, and the sauce was not put on the burger. I called and they did apologized and offer to fix it, which I appreciate, but none of us are driving back out to get the corrected burger. It should have been right the first time. Things like this, forgotten ingredients, seems to happen almost every time we order lately.. Which isn't very often anymore.
