I'm sure everyone has found something they didn't like about a country - we have had some 'funny' tubs as well - including one at a couchsurfer we stayed with in Genoa - the tub was a bit narrow and curved in noticeably towards the bottom - I almost toppled over. Also not fond of the wet room of one we stayed at in Atrani...but it didn't mean I didn't enjoy my time there.
I'm also not fond of the people on the streets trying to sell you cheap stuff, the scammers or all the smokers when I'm trying to enjoy eating outside - doesn't mean I'm going to stop going to these countries. I agree the comment was a bit harsh. I'm sure those commenters found something they disliked about places they've been, whether it's traffic, no kettles in their room, lack of public transportation, or - say - something as weird as shallow bathtubs or bathroom stalls that have gaps (yeah, I don't like that here either). Should I say that you shouldn't travel to North America because you don't like the gaps in the bathroom stalls?
As for New Brunswick - photobearsam - we ALL know NB is just somewhere you drive thru to get to the much more interesting Nova Scotia or on your way to Maine or Quebec (oh yeah - I said it!!) It's a long held tradition that NS doesn't like NB, just as it's a long held tradition that anyone west of Ontario thinks Canada stops existing at Quebec.
Tongue firmly planted in cheek. ;)
