I'm a fiend for drug names. I'll be like "oh noes your drink might have flunitrazepam in it" and people will be like "What" and I'll be all "Dateraep, you know?". "Oh you mean roofies". "Oh yea, that's the other name for them!"
Relationship interested? If all you have to spend is $400 then money isn't the key to your date with destiny. Rendezvous interested? Don't care if you perpetrate a lifestyle that you can't maintain? Take a trip to the shore. Must be several hours away from home. You take her for a walk on the beach and through some seaside markets, followed up with dinner at a NICE restaurant right there where you've been hanging out. Order the most expensive champagne on the menu but don't make it out to be a big deal. Far away from home + early romaticism/late night + alcohol = hotel room. Don't make me explain the rest.
Best idea so far. Walking on the shore, holding my shoes in one hand and her hand in the other is going to be so romantic. The snow and ice between my toes, perfect winter sunset. Thanks.
Sorry, poor people are unable to pick up women. It is unlawful. I am very sorry. The hooker idea sounded like a good bet.
