I struggle to understand the psyche of a purchaser of F class tickets, who has the foresight and the inclination to make trips to the dollar store and keep a personal stock of bulk travel toiletries.
Given my recent reference to Dollar General above, I'm wondering whether you're referring to me? If so, I find those travel shaving foam products great value but more importantly, ideally suited for HBO travel in any class. I've traveled from the US to Europe, Middle East, India and the Far East without once having a problem through security. I don't quite understand your point though. Are you suggesting that those traveling F should only purchase top end shaving foam? I don't use cheap disposable razors as I find they leave me in a bit of a mess.
