Use quotation marks when using Singlish on signs

Although Singlish may be inappropriate in formal situations and sometimes unintelligible to people from other countries, it has its advantages, often owing to its succinctness (Singlish signs on new bus, can or not?; March 14).

Tower Transit deserves praise for having considered the concerns of those opposed to the Singlish signs, by using standard English for the explanations.

Perhaps placing the Singlish headings within inverted commas would help emphasise that colloquialism was used intentionally.
