Junket -- That's the word I am looking for

A few hours ago
I ordered two tacos "to go"
But since it was free
I wanted to eat three,
that put me thinking
about the word for such hoodwinking.
It was something in barrons or kaplan easy to forget
for ppl who take a trip on someone else's budget.
Junket it was
and yeah that was the cause,
why I tried a medeterranian cuisine
or got picked up in a limousine.
It feels great when all you can spend is paid,
except for expenses of getting laid...
when you dont have to think about money
and get out of your cave of parsimony.
And now I guess people get to know
why I publish every time I want to get away from the snow.
