better ideas for chance encounters than a bar or coffee shop:

 

a storm is delaying our flight home and i'm afraid of thunder, please talk to me while we wait

we're both in small claims court and i got into a huge fight with the person suing me but you stepped in to hold me back before security got there

i drove two hours to the closest video rental store that's still operating and you were checking out the only copy of the movie i was after

i hit you with my car but luckily you're okay, but we should still exchange information i guess

our friends that we came here with went off together and now we're making awkward small talk

i was worried about buying something off of someone creepy from craigslist but oh no you're hot

my friend talked me into playing a drunken game of spin the bottle even though we're all adults and now we have to make out..

we both decided to take a [yoga/fencing/ cooking etc] class and we're the only two assholes not taking it seriously and everyone else is giving us dirty looks but we keep grinning over at each other

my date just made a scene in public and got arrested and now i'm stranded in a city without a ride home

sharing a cab together

you're trying to get me to sign a petition and i have no idea what you're talking about

you're drunk at this festival and dancing on the table and when you eventually fell i caught you

i tried to get a part time job at this place right by my house but they hired you instead and i have to see you every day when i go there now

blind date!

my roommate is your ex, and your roommate is my ex, and i caught them sleeping together and told you so now we're pissed off and going on a date to get away from them even though we didnt really know each other before now…
