London = rank

No, London's not rank (slang), Londoners and Britons in general just like to rank things, which is a kind way for saying 'they like to impose the class thing on everyday situations much like they did for their colonial occupation of India et al'.

Here are some rankings:

Grocers:
Kensington High Street Whole Foods
Waitrose
Marks & Spencer
Sainsbury's
Tesco
Iceland.co.uk
Dadyal (the 24-hour convenience store next door to my flat. I personally rank this much, much higher. At least above Marks & Spencer -- how can you be #3 and not carry peanut butter?)

Public Transport:
These guys who ride a scooter to wherever you are, fold it up and put it in your trunk, and drive you home in your own car (useful only for the drinking crowd)
Addison Lee Taxi (on demand car service)
Black Cabs
DLR (Docklands Light Rail)
Overland trains, ie. Thameslink
Tube/Underground -- Metropolitan and Hammersmith & City lines
Tube/Underground -- everything else but the East London line
Bus (kind of a hierarchy here too -- doubledeckers, extended, single, night)
Gypsy Cabs
Tube/Underground -- East London line

Sport:
Cricket
Tennis
Rugby
Football
Formula 1 (Wait nevermind, this isn't a sport. It's more just an exercise in burning as much fuel as possible in as short of time as possible.)
