Stress relief

I can't walk past these massage chairs without popping two dollars in the slot for a few minutes' massage.  What a bargain!  I've met some interesting people there.  The last one was a young lady who was quite verbal in her response - calling out "ooh"  "aah"  &  "ouch". Her  massage seemed to go on forever so I asked her how much she put in the slot.  She said "eight dollars" !!  Incredulous, I asked why. She said she thought she had to!  She had four times the recommended length of time having her spine pounded.
