the cry of the soul

Hello world!!! My name is Alex, I'm 27 years old. I have 1.5 years working as a waiter.
Work in the North of the city of St. Petersburg in the restaurant.
90% of people do not leave a tip, and if
you from the table that sat on $ 300 (large company) will leave 1-2 $ you already think well at least something. I am ashamed for our people, for their education.
I was not born in a rich family, but sometimes we went with mum to eat delicious meals in cheap restaurants, and it got me since childhood, taught that
put the waiter left to tea as thanks for having us fed and kept the table clean for our comfort.
I hope you who reads this post, always leave a tip waiters. Thanks for your attention!
P.s.-I am fed. ...
