Sparks came in this can because it tasted like battery acid

I remember in my mid twenties I went into a more upscale bar to see a blues jam that was kind of a big deal. I confidently walked up to the bar and asked for a jager bomb and the bartender just looked at me for a second and said “No” and then just kept looking at me. So I awkwardly asked why, and he said it was a kids drink and I was in an adult bar. Btw there were other people there my age. It was just kind of snooty place. He then poured me a whiskey neat, on the house, and told me it was time for me to grow up. I didn’t really know whether to be irritated or not but I took the free whiskey lol. At 25 I wasn’t super impressed with room temp whiskey but I drank it and watched the jam for a bit and then left and went to my regular bar where I played music and had friends. I do take whiskey neat now sometimes though.
