They are solar powered microwaves, only used between the hours of 10.45 and 11.32, sort of breakfast only. Instead of using actual micro waves the microwave type thing actually houses a miniture austrian dragon, named after the person who built the microwave type home for the dragons to live. The dragons wouldn't have it any other way, they make breakfast at those times for them selves and the cabbies can help them-selves. They fly about and mate with russian ostriches on the 3 saturday of the 6 month of each year.
tl;dr, wigan-acolyte.
