1. It is my understanding that hot dogs are not barbequed. Make sure the correct appliance is used. If only a barbeque is available, consider replacing the frankfurts with sausages.

2. If you are trying to cater toward anyone, the food you offer should also match. Eg. organic vegeburger or tapas spread for the middle class hippy-wannabe that needs a hybrid car so as not to offend their friends about buying an earth destroying vehicle. They already feel the pressure to tread lightly, and may be a little more than put off when they discover that purchasing from your dealership will contribute to the inhumane treatment of animals (not to mention that hot dogs and sausage sandwiches are just too lower class, unless they’re organic home-made rosemary and lamb sausages with a homemade tomato relish on sourdough). By the way, you should also be sure to offer vegetarian and vegan alternatives, cooked on separate barbeques, as only offering one could offend some people – vegetarians may be concerned that they are not getting enough dairy or egg; or conversely they may regard themselves as lacto-vegetarian, meaning they will have dairy, but not egg, and may require the vegan burger. And vegans are just plain paranoid and weird. Both are suspicious and will hate you if you make an incorrect assumption about their diet or beliefs. First impressions count.

I once heard that a significant percentage of SUV sales are from people who want minivans but just cant stand the image that they portray.
