2. Chewing Gum
Americans chew a lot of gum, and it can be a problem when they don’t dispose of it correctly. There is probably no public table in the country that doesn’t have at least a wad or two pressed underneath it. It’s gross, but the sale of gum is too profitable to stop.
In Singapore, however, a country known for its cleanliness, they aren’t having it. Chewing gum was banned in 1992 in order to help keep the streets free of sticky detritus. The penalty for violating the ban is steep – get caught selling gum in Singapore and you could get up to 2 years in prison or a fine of $1,000.
