Geek Bar

If my regex-fu is still strong, that would be:
Coffee 1.50
Beer 2.40

[Andy Palmer]

That's what I got too, although the biggest joke was that I took the time to work it out =D

Looks like I'm a half-geek: got the 1.50 and 2.40, but failed at recognizing $1 as something else than "1 USD".

Real people use \1 and \2 anyway!!1

Biggest joke IMHO: There is no such thing as a "Geek Bar"

This is Perl regular expression and using $1 and $2 seems perfectly valid as per "perldoc perlre", section "Capture buffers" examples.

Also try this:
perl -e '"1239.28912121.5011.2129829.02.4021" =~ m/2(\d\.\d+?)1.*0(\d\.\d+)2/ ; print "Coffee $1\nBeer $2\n"'

It works perfectly with $1 and $2, but not with \1 and \2.

\1 and \2 are to be used in substitutions. Outside the regular expression, they're meaningless, so you must use $1 and $2

The joke, to me, is that people who grok regex get an intelligence tax of 50c on coffee, 40c on beer :)

Better to pretend you don't know regexes, and just give the USD amount shown.

If the barman grumbles, say his sign never stated a currency, so you're paying him the equivalent in $CAD.
