> It is not reasonable for them to say "sure, here's your alcoholic drink as you requested" and give them an alcohol-free substitute without telling them.
replyYour analogy doesn't work because: - they tell you the rules at the entrance of the bar - they totally tell you when they give you a substitute
The only issue is the bartender asking you for your money before serving you the drink really but again, this is known since day 1 by the customers.
Your rebuttle seems to be arguing it's okay for a bartender to simultaneously say:
reply"This is alcohol"
And
"Or maybe it isn't alcohol."
Or to rephrase it, "They tell you the rules at the entrance, they then tell you they don't follow those rules and they are totally serving alcohol even if they are not."
No they tell you at the entrance that at any point they may unilaterally decide to replace the alcoholic drink you ordered by a non alcoholic one.
replyYou can decide you are okay with that or not but they aren't dishonest. I wouldn't enter that bar personally but if you do you cannot really complain. It is like complaining because you haven't won at the casino.
