No.
But since this is posted in dating advice and you highlighted being single, I'm guessing you mean for the purpose of finding a dating prospect.
Don't do this.
Instead, find a bar that you like (you might have to try a few first).
Then just hang out and have a threshold to stay for maybe two drinks max on your first visit.
Be cool to the bar staff and anyone who strikes up a conversation with you. Leave a good (but not exaggerated) tip.
Do this a couple more times at the same bar and you'll probably start being seen as a regular.
Eventually you'll naturally meet dating prospects through the social circle you've built up (without coming off as creepy or weird).
And even if you don't, there's a good chance you met some cool and interesting people along the way.
