Do not mess with old people !

 Two businessmen in a new shopping mall.....

were sitting down for a break in their soon-to-be new shop...As yet, the shop wasn't ready,
 

with only a few shelves set up.

One said to the other,
"I bet any minute now some pensioner
is going to walk by,
put their face to the window,
and ask what we're selling."

No sooner were the words out of his mouth
when, sure enough, a curious old woman walked to the window,
had a peek, and in a soft voice asked,

"What are you selling here?"

One of the men replied sarcastically,
"We're selling ass-holes."

Without skipping a beat, the old dear said,
“Must be doing well..... Only two left!"

Lesson here: Do not  mess with old people !
