Cryptic sign, but we all understand!

I spotted this sign at the supermarket. I have walked by many times but never paid attention to what it said, until that day. What language is this? Even SMS language does not have such abbreviations. Must be a unique combination of Singlish (aka "Singapore English) and fast typing.

The amazing thing is, we all understand the meaning. Wait a bit. The sales person will be back shortly to help you.

Happy shopping!
