I had a performance review at work the other day, and my manager told me that i was a "blessing" to our team because of the way i treated our clients and my teammates. He mentioned one example: when a client came in to photocopy 20 booklets for his business line, and while we only have to point to the colour copier and show them how to use it (if they don't know), i got him a chair, and gave him my "dining out" in brisbane magazine to read. The guy (who i found out was the EL2 of his business line - pretty high up) emailed my boss to tell him how nice i was to him.
Made my day. :D
