I know some friends who think they need alcohol to have a good time. One particular friend is rarely without a drink in his hand on weekends, including when he is on a date. I ask him all the time to cut his drink intake on dates to 2 drinks and he never listens. If you are dating someone drunk all the time, what happens when you are sober and you two no longer click?
I believe if you must drink on a date it should be in moderation. Dates are fun when they have activities, this means hand eye coordination and balance can be used. If you are tipsy, how charming can you really be? Do you usually have a drink on a date?
What would you do if your date drank too much? Is it a red flag for you? Would you go one another date?
