Yeah, tea is big here, and so are the teapots. After being here for 2+ years I'm still surprized at a few things.
1)They sell 6 liter (1.32 gal.) teapots. That would be the one on the left
2)They sell 7.5 liter (1.63 gal.) teapots. That's the one to the right.
3)That if they fill it up you could carry 7.5 kg. (16.5 lbs.) of boiling water.
4)A Cambodian might feel comfortable pouring from a full teapot of that size and weight.
I just say'n, I would definitely have to get a bigger tea cup.
Concerning corruption... This white drop box is located on the NE corner of Monivong and Kampuchea Krom in Phnom Penh. It is arguably the busiest intersections in the city and therefore the whole of the country. If you look closely you can read the gold English writing "FOR REPORT OF COMPLAINTS ON CORRUPTIONS". What you can't see in the picture is the 3 police men that were 10 yards north of the drop box looking very concerned.
I don't get the feeling the cops here like that box much.
