Does everything have to be the same as where you come from?

Is it such a bad thing when in fact their tips over the month is more than their salary?

I repeat...local (and some other) ladies will not be comfortable going into a small shop with males only inside. There's a cultural issue here.

I know for a fact that many people tip generously as they know it will bring much needed income. It's a form of charitable giving.

If you insist to go into the shop yourself please tip generously so they don't lose an opportunity to make some extra money.
