Mysterious $1 Loss

Haha... i was buying a ice-cream ytd at Toa Payoh Mac and then i paid $2 then got $1 change... then when i reach home that $1 coin is missing. But i remember correctly i put it in my pocket mahz... maybe i dropped it or something... =X

Anyways... i take it as "po4 cai2 xiao1 zai1" lah... =P

To all those taking mid-years and ICAs, JIAYOU!!
