Was my drink spiked?

A few weeks ago I was at a bar where I know one of the bartenders well. She made me a drink and surprised me with it and said it was free. It tasted pretty normal. Then like not even an hour later I was totally out of it. I got there at 8, had the drink at 8:15ish and by 9:30 I felt awful. Couldn’t think straight and barely talked the whole night. Had no concept of time until around 12:30 when I left because i felt like I was gonna fall asleep. I said goodbye to the bartender and she seemed frustrated I was leaving early.

Then for a whole 48 hours after that night I had a hangover and still couldn’t think. I went outside like two times my entire weekend. Like two entire days and I felt out of it.

Last weekend I went again and a different bartender made me the same drink. I felt awesome the whole night. Felt normal all night and no hangover at all the following day. What do you think
