From here.
After a weekend in Sin City in which there was nare but a sober moment , I ended up here with some of my British (and American) coworkers a few days later while the detox process was taking place, and in the process ended up breaking a cardinal sin whilst having dinner with our friends from the other side of the pond.

Waitress: “And Will you guys have anything to drink?”
Boss sitting across from me: “I’ll have a Stella please”
Guy to his left: “Guiness for me please”
And to his left: “Stella”

A couple beer later it was my turn in the spotlight, while the others were conversing among themselves.

Me: I’ll have a *whsipers* water.
*silence*

I could feel the angry glares coming down over me, as if I had just insulted the Queen.

Thinking on my feet I said: “I mean I’ll um, have an h20 from the draught on the rocks please”.

But they weren’t phased by my attempt at cleverness.

Damnit.

After a few minutes of being scolded with a lesson on what good dinner table manners are when you’re out with Brits, with my pleas to them that any trace amount of alcohol would effectively render my liver useless and kill me falling on deaf ears.

Eventually they got bored with me and we got along to taking orders.

We started with some oysters, and I got myself a Celtic burger.  The oysters came with a reddish sauce and white cream on the side, and I thought to myself “hmm, I’d never had oysters served with mayo before”, so I topped one of my oysters with a huge dab of it.

I dug it out of its shell with my fork, and being starved as I was, I decided to suck the whole thing down in one quick motion.

…

“HOOOOOLY SHITTTT!” I exclaimed, as a rush of fire went through my nose, down my mouth, into my esophagus and basically destroyed all of my intestines.

“What the fuck was that?!” I screamed.

“Horseradish,” the group replied in unison.

-_-

Otherwise, aside from that moment of ignorance and the death wishes put upon me earlier in the night, the night was quite enjoyable.  The burger and chips were very delectable, and the oysters, once I went conservative with my “mayo” hit the spot as well.

Then by the end of the dinner, and me feeling like a man now, with that manly horseradish incident and after finishing that manly burger, I manned up and agreed to join the group for a shot of manly Jager.

It felt great.
