Hehe, cheers, my friend! 🍻 I remember, but I don't remember precisely where anymore, in an Irish pub somewhere in Europe (no matter where I am, I try to find an Irish pub, and sometimes I have time for that, but not always...)
Anyway, to cut a long story short, after I had a couple of pints, I had to go and drain the water, and the toilet was in the basement; when I walked down the stairs, there were similar Guinness messages left and right :) 🍻😜 !INDEED
