I know it’s rude, and I’d not do something like that in my life!
I was always a fair person. When somebody buy me papers, pencils or other lovely things I always give a custom design in exchange (I do this with my family, and my friends too!). My boss thinks I’m stupid at times like this, but my conscience tells me this is the least thing I should do for others when they help me.
Aw, thank you so much! xx
