What do you do to show appreciation for kind acts?
like someone holding a door for you or helping you with groceries...
Smile, and say "THANK YOU".While looking in the person's eyes.
It's a thing called "Thank You"
Say "Thanks" and smile, and try to be courteous to others yourself.
A "thank you" and a smile would be fine. On Ask.com, a helpful star is necessary :)
Telling them thank you and do kind acts to them.
you can say thank you or if you really want to go to the extreme of being nice for helping you with your groceries then tip them
a smile and a sweet thank you :)
I smile and say thank you if someone is polite. If some one does a favor for me, that is more than just a kind act, I cook something homemade for them to bring home for dinner.
Say " heres 5 bucks buy yourself something nice"
laugh about it maybe. smile and thank them. on ask, i'll just say thanks and maybe try to have a short conversation with them. for some people it turns out to be more than a short conversation.
