is a bit of spanking on the playroom bed considered normal at a swinger club or do ppl think it's weird

genuine ask. couple in our late thirties, been to a few swinger clubs in london and one in dublin, mostly the more sociable ones not the hardcore kink end of things. at our home club last weekend a couple we'd been chatting with for ages finally clicked with us and we went to one of the bigger play beds. things got going, soft swap level, and the other husband started giving his wife a few proper smacks on the bum while she was on top of my dh. like... not light taps, proper open hand spanking, you could hear it across the room. now half of me was thinking this is totally fine they're into what they're into. but the other half noticed two other couples kind of glance over and one of them moved beds shortly after. so im wondering if the etiquette at a regular swinger club (not a kink club, this place is very specifically marketed as LS not BDSM) is "keep your kink at home" or whether a bit of audible spanking is just part of what happens. we've been to torture garden as guests and obviously there it's a different planet. but at a vanilla-ish swinger club is impact play actually welcome or is it one of those things where technically allowed but socially raises eyebrows. asking partly because my dh and i are into a bit of that ourselves and now im wondering if we should keep it for a separate venue, or if we're overthinking it and the eye-glances were random.
