Let us say hypothetically after years of tailgating, you decide the best way to do your tailgate is everyone brings $7. In return you get chips and some kind of dip, appetizer, lunch, some kind of booze and sometimes another thing here or there. You also never are asked to chip in for forks, plates, etc. And you honestly spend more than you collect, but you are happy to do it. Primary reason? When you tell half a dozen folks to bring something it never goes right. One person forgets a vital ingredient. Or you ask for burger fixins and someone brings a whole tomato and whole head of lettuce (whereas you decide it is easier to do all the prep work at home the day before than bring extra knives, cutting boards, etc). If you have tailgaters that ignore your request for $7 and keep bringing food (that honestly is not needed), how do you broach the topic without offending anyone?
