I've seen cups with the tops available for taking hot drinks away with you at UA Lounges in the US. I believe that Lufthansa also provides (or provided) a selection of snacks and drinks to take with you on your flight, so I don't think it's as clear cut as you think. If passengers are accustomed to using such lounges they may not be aware it's against the rules at BA lounges. Is it though?, that's another question!
