I was wandering by the local Quality Food Store (QFC) recently and noticed that due to it being spring and everyone wanting to BBQ they had a nice display set up with a grill and many bags of charcoal brickets but something was off. Upon closer inspection the grill they decided to surround with brickets wouldn't even be able to use them... because it was gas.  Maybe they have a package deal - if you buy the grill you get a free back of charcoal....
