I did the legals for the “Aquatics Centre”, and I don’t remember the name of the building ever aggravating anyone as much as the OP.
However, given that you managed to squeeze in an offensive word in 4 word thread title about the name of a building, I’d guess you probably get irate about many trivial things.
It’s not that pretentious at all, in fact if you have a quick google of “aquatics centre” you’ll see that not only is the term used in this context for water sports centres (doesn’t have the same ring to it eh?) across the world (including most major cities in the UK), but it has also been used specifically in Summer, Commonwealth and Olympic games across the world since 2000.
If I go to an aquatic centre I would expect to see some reef sharks or a couple of dolphins.
No, that would be an aquarium
