The premise of your question is a fallacy; many peope BYO and also order beverages from the restaurant; I can't remember ever having BYO and not also drinking something else.
There are 4 questions - which one has the fallacious premise given that I actually mentioned use of glassware and corkscrew? If the fallacious premise in one of the questions is that you aren't ordering any beverages lets change it to you aren't ordering as many beverages as you would if you hadn't BYOd which doesn't really change the substance of the question.
