Any foreigner who is not a moron knows that you should always refer to the Chinese first and
only ever read the English translation as a last resort.

Of course they should ! After all, most foreigners can easily read and/or write Chinese characters, and those that can't, well....they're 'morons', right?

The only people who are 'morons' are the one who use outdated electronic translation tools that translate such Chinese characters as 干 (dry) into 'f*ck'.

If these 'morons' are prepared to go to the time and trouble of putting English 'translations' onto menus then they are obviously attempting to cater for foreigners. Therefore, IMHO, they should spend a few extra bucks on getting the translation checked before going to print. That way American tourists will have nothing to laugh about!
