Sure, I will. As a few others mentioned, BMC often is what a host offers, and I will graciously accept it. Sometimes, at a pool party or similar situations, something light and crisp like that is just what the doctor orders. No doubt, there are better options than BMC and their ilk, but you go with the flow, if for no other reason to be a good guest.
If BMC is the only beer option, but there are other options (such as wine or liquor), I often will "shift away" from beer for the rest of the time after having a beer or two.
Now, I cannot remember the last time I just ordered such a beer at a bar or restaurant. And, other than picking up beer for sensory training kits, I cannot remember when I last bought any at a store.
