That's not 50 feet!
There are signs around the entrances at a nearby mall I wander to occasionally which state: "No smoking within 50 feet of mall entrance- The Management"
I have now stopped to stare at that sign at least three times because people have been standing beneath it, smoking. Now, I'm no good with measurements without a ruler, but I sincerely doubt they'd post those signs if they were already 50 feet away.
Usually, I stop walking and stare at the sign, then the smoker, then back to the sign. Today marks the first time the smoker's taken notice of me doing so.
M: "See the sign?"
S: *garbled words, most likely to the effect of: "It's raining, I'm not standing in the rain to smoke"*
M: *thinking* "And yet, you have an umbrella in your other hand." *grumbledina as I walk away*
"I call murder on that!"
