For a few minutes of diversionary delight, go check out Kate the Great's post with embedded clips of Wendy's training videos. These are classic early '90's employment videos, set to music in order to capture the attention of their teenage new hires. The two-minute video on how to serve hot drinks is particularly instructive. Tips on how to pour a cup of coffee include the lyrics:
Gets a lid
Tastes so fine.
And from the segment on serving hot tea:
If they want lemon
It's very nice, don't think twice
Give the guests
Their juicy slice.
