is it possible this was a *really* old hotel which might have had some NEMA 2-15 outlets in use? Ive seen those warn out to the point one might get a round pin into them...
It still doesn't make any sense as UK and Irish appliances don't use round-pin plugs. If it actually was a UK appliance it would have had a BS1363 plug which, without the use of a sledge hammer, is not remotely compatible with any NEMA outlet I've ever seen.
That's what you would have on a typical DVD player over here :

There is no 2-pin version as the ground/earth pin is required to open the interlocked shutters on outlets here.
That's what's used in Continental Europe for appliances under 2.5A load :

It's not used on UK or Irish appliances.
The story just doesn't make any sense. I'd say it's a faulty adaptor of some sort.
