In Singapore, chewing gum is prohibited. This rule was introduced because of the high cost and difficulty in removing stuck chewing gum from public premises. In particular, chewing gum stuck on the Mass Rapid Transit train doors stopped the trains from moving. It happened a few times and those were a few times too many.
在新加坡,嚼口香糖是被禁止的。之所以設立這樣一條法規,是因為清除公共場所的口香糖會花費很高的成本而且很難清除。特別是當口香糖被吐在大型的高速鐵路列車的門檔上,會阻止列車前進。這樣的事曾經發生過幾次,而這幾次對政府來說已經夠多了。
