In Detroit many of the fast food joints have the worker area behind bullet proof glass. As for this crazy lady, I would say that I would remake her burger if and only if she gives me the other one so I can throw it away. As a side note I also do not like tomatoes but I take them off myself as it is very easy to do.
she did bring the bag back and thru it at the worker. I assume the burger was in it.
Click the link I posted up above. It's only 27 seconds long.
A few years ago, someone posted an article here at Free Republic about a municipality that had made it a code violation for "places of business" (incl. all-night liquor stores) to have bullet-proof glass partitions separating customers and clerks - on the grounds that (get this) it was "racist," "offensive," "didn't reflect the community's values," etc.
No thought to the idea that a for-profit business doesn't install something like that unless it has to / unless it makes economic sense.
