Not sure if I have that- I'm BA silver and doing ET this time (already retaining silver going 200 TP over the minimum threshold with all my trips this year). I do want to shower again for the second time that day (OCD lol ) as I'm probably not doing so again until I reach the galleries lounge the next day at 6am or so attending the Christmas drinks meetup and booking a shared hostel dormitory room for a couple hours of sleep around the Victoria/Green Park station in London.

Hopefully the showers are decent and clean at least!
