I get it. Around here some of the Lowes home centers have a Dominics sub trailer out front. The smell off grilling peppers and onions is very attractive.
I know this, when it first started there were lines at those things all the time. After a while, the novelty kinda wore off and I don't think they do near as well as they used too. They seem to do better on weekends and now days I'm used to seeing one or two folks there at any given time and about 6-12 on weekends at any given time.
I only offer this because I am one of those nuts that seems to be in a home center at least once a week or so and notice such things. Just thought I'd toss it out to you for consideration.
