How to save money

In Sweden
At the tourist center:
A 3 day metro pass is 200 CHF (~<20 euro)...unless you are 19 or under, and then it's only 120 CHF.
"Oh darn we're 20!!! but we're Asian we look young so no one would care hmm what should we do."
*much discussion about which metro plan to do*
Finally:
"Would you sell us the 19yr old pass?"
"Yeah."

At random train station candy store:
"Wow this chocolate covered marshmallow thing is 3 SEK less than at the real candy store!!!"

In Switzerland at a MAMCO:
"How much to get in?"
"8 SEK (~>8 USD)"
"Is there a student discount?"
"That depends...what do you study"
"Ummm art. . .of course!"
"Ok it's free then!"
("Do you think he knew I was kidding?" "It's hard to tell! He actually checked our IDs!")
