Another roach story...
I once worked at a movie theater. I had been there for years high school and then college breaks, with no roaches at all. Then, suddenly, WHAM! It was like the attack of the killer tomatoes, except it was the attack of the killer roaches! They were ALL OVER the concession stand, marching single file up the soda lines, crawling in the spaces between the sour patch kids and the jujubees...even stalking the perimeters of the popcorn cases (though not actually going inside, maybe the heating fans kept them out?). They would run across the counters and we would catch them under a small popcorn cup and smush them later. Behind the counters, in the cabinets where the drink and popcorn containers were held, they were swarming.
For whatever reason, we had to wait a few days for the exterminator, and for another reason (let me guess, profits!) the concession stand was not closed. The thing that amazed me was that people still bought the food!! They could SEE the roaches, but they would still buy the popcorn. I would TELL people that there were bugs, but it was like they were in this sugar coated butter loaded daze...they did not care about the bugs!! They were at the movies and they WOULD have popcorn, even if it was "extra crunchy!"
Interestingly, once the exterminator came (and the stand was closed for two days), we never saw another roach for the time I worked there.
