Tipping Signs

These are supposedly actual signs that have appeared at various locations.

At a restaurant in New York: "Tip-ing is not a city in China."
Here is a great sign I saw in the grocery store: "Snickers, 5 for 1.00$.(limit 4)"
On a dock in Juneau, Alaska: "Safety ladder, climb at own risk."
Seen on an electrical appliance store in Spokane, WA: "Go modern! Go gas! Go BOOM!"
Emergency Evacuation Plan posted in various places around my office building: "Run like Anything!"
Biggs Septic Tank Service (near Nashville Tennessee): "Call Monday thru Friday, sorry, we haul milk on weekends."
Sign on the wall of the office of an ethnologist: "Beware of bargains in 1. Parachutes 2. Life preservers 3. Brain surgery 4. Eye Care"
Billboard sign on a highway coming out of Austin, TX: "Nobody reads billboards.... But you just did :)"
