Helpful cashier

My daughter went to a drug store in Taipei to look for a specific medication. She could not find it on ths shelf. She approached the cashier.

The cashier said that the medication is not sold in the store. Without being asked, she immediately told he customer where she can buy it from another nearby store. That is helpfulness.

Why is it possible for the cashier to be helpful?
1. She is a local person, who knows the customers and their lifestyle
2. She has worked there for a few years and acquired good knowledge of the product.

I shall do some research to find out if the cashier earns an adequate salary. This will encourage her to stay in the same job for a long time.

There are lessons to be applied in Singapore, if we still aim to be a gracious society.
