I worked for a multi-national convenience store chain many years ago. It may have changed since but, the corporate training material encouraged staff to offer police officers free coffee and self-serve semi-frozen drinks. The openly stated reason was to encourage their presence and deter theft, loitering etc. It was my experience that most officers politely declined our offers of free stuff. We were also allowed to occasionally make the same offer to whomever we wished.

In Alberta we used to have "Honest To Goodness Spread". It had similar packaging to "I Can't believe...", but the word margarine did not appear on the container anywhere. The 'spread' had no yellow food colouring and was white.
