Flip-flop broke

Damm my family doc only opens on 17th Feb but I had to grab some antibiotics for my inflamed throat. Hence I went to another clinic nearby. The consultaton+medicine cost me $65! I felt it was so unnecessary that the doc took my height n weight n blood pressure etc...!
Am on MC today.. and Whine i cant believe it! My pair of havaianas' broke when I went out to ta bao lunch at J8. The strap on the right flip-flop came off just when I walked passed Long John Silver.
I tried to fix it there and then but couldn't. Instead I attracted stares from this group of girls from Bishan ITE.
It was argh.. soO unglam.
I had to drag my feet to 77th street just to get a new pair of slippers. I requested for the cheapest pair but it didnt have my size. Only Billabong has size 10. It didnt fit well too.. I realised my left foot is slightly longer than my right one. And the slippers' $22.90. So expensive!
All these hidden and unexpected cost...
