I offer up last Sunday as a prime example.
On just about any Sunday as soon as church services are over the people are out of there like the place is on fire. BUT… You mention that there is some free ice cream being served in the kitchen and it quickly turns into a prairie dog killing stampede. I almost got run over. I don’t know if it was the words “ice cream” or the word “free” that got them all moving. I suspect both.
