Do you want to know about my tipping policy?
Don't you think tipping culture has gotten out of hand?
But I think tipping is also important because it shows how grateful you are for the hard work of the staff.
It is good that you want to show your appreciation but you can always change your mind later if you feel it is unfair. It would be okay to change your mind if things become different.
I never change my mind about something that I'm sure about.
You should always be willing to change your mind about anything, even something you're entirely sure of. It allows you have a better belief system if you can hear out other people's views.
