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。之所以设立这样一条法规,是因为清除公共场所的口香糖会花费很高的成本而且很难清除。特别是当口香糖被吐在大型的高速铁路列车的门档上,会阻止列车前进。这样的事曾经发生过几次,而这几次对政府来说已经够多了。
