又是警惕信函- - 真假？？

我又收到一则电子信函。
近来都收到这一类信函，不贴出来内心不安。
贴出来又好像是- 怕我们的社会不够乱，要插上一脚让大家心兢胆跳。
还是希望大家小心为上。。。。

Dear all,

If you get RM10.00 in your car door handle, use tissue paper or cloth
to remove it without opening it and if possible bag it. Drive away
immediately.

Don't check the note until you are in the company of your friends or
relatives. The note could either contain powdered drugs to knock you
out or make you wonder if some guilty motorist compensating you for a
knock or scratch on your car, while you are still wondering, the
robber(s) will attack you as you check the car.

This had happened in Johor.
