It has been pointed out time and again that a common purpose for misused quotation marks is to create emphasis. This flier, posted in a nursing home office window, has emphasis out the wazoo.
My favorite:
"chips, salad & yer'Hot Dog...!"
Extra points given for using a far too unused contraction (yer') twice on the same page including a rare yer'Hot.
"Bring yer' appetite!" clearly means, "Bring yer' $3"
