MARY THE TROLLEY DOLLY

"What's your occupation?" Richard said 
"I'm a trolley dolly" Mary replied turning red 
Mary goes up and down on a train all day 
She will serve you snacks to keep your hunger at bay 

Mary makes a fantastic cup of tea and coffee too 
However I would avoid the sandwiches if I were you 
Crisps and chocolate are also on the trolley rack 
The staple food of the great British snack 

Richard was not put off by the description of Mary's job 
He respected her more as she worked for an honest bob 
Money they say makes the world go round 
In the words of Cabaret it makes a clinking clanking sound
