Please re-sting my tennis racket

I noticed this sign only after walking past it numerous times. Suddenly, it caught my attention. Of course, the grammar is wrong, but that is just minor compared with what they are advertising.

First, "sting" refers to an insect attack like that of a bee or hornet.

Second, a bee sting only happens once because the bee loses its ability to sting after one attempt. Therefore, there cannot be a "re-sting".

Third, tennis rackets cannot be stung. They are inanimate objects. They cannot feel pain.

A tennis racket, however, does need to get a new set of strings every so often when it is used frequently. This process is called "restringing". This is what the shop specialises in: restringing tennis rackets. Unfortunately, either the owner cannot spell or did not notice the typo error - for many years!

A minor error can mar a company's reputation for life. Let us check and re-check before it becomes "cast in stone".

Happy proof-reading!
