Yes I noticed last time I was in the “underground” the vast odors. No place like Britain if you like the effervescence of hormonal glandular smells.
The curry and beer lingering from the night before is always a goody. :p
Ever been to France? That being said, the most disgusting habit I’ve personally observed by a Brit was when a nanny we employed from Sheffield was washing our dishes and putting the soapy cups and plates into the drainer without rinsing them. She told us that’s how she was taught to do it back home.
