Talk to the Friendly Stranger

Spending few days in Indonesia few weeks ago really makes me miss to talk to the "friendly stranger".
Been staying quite some time in abroad, really makes me can't ressist to have a light chit chat with stranger like they way it is in my hometown.
I do always enjoy to have a quick conversation with a cashier in a small supermarket near my house & start it only by saying "How's today?? Many people shopping here??".
It's definitely not a common situation in the country I'm staying right now.
