Of course these cobblers charge so much cheaper than those in air conditioned malls. To replace the rubber of heels cost about $2 - $3 while in the malls would cost so much more.
The cobbler would offer the customer a seat while he mend the shoes. If you are not in urgent need of the shoes, you can put the shoes with the cobbler and collect another day.
I used to have my shoes repaired by them but I dont anymore cause I dont ruin my shoes anymore in disco....lol. During my teens, disco is the "in thing" and we used to dance every weekend and our poor shoes cant take it...lol. My disco friends and I have very good memory of the good moments we had back then but now we are all mothers of grown up kids. :) It is our kids turn to go dancing.
