The Sacred Cow

I'm now waiting at the gate for my flight to LAX. It should start boarding in 40 minutes, and take off in 70. The airport staff are using the doors here as a shortcut into the arrivals system. They seem to be feeding people who somehow accidentally escaped the customs and passports control back in.
I bought a bag of beef jerky in an attempt to lighten my load of Canadian pocket-change left over from buying a meal and a drink.
I think I've been coping surprisingly well for a half-drunk, sleep-deprived tourist who has never seen this weird little currency before.
I'm sitting in a little enclove with an Indian-looking Mother and her Sons, I can't help but feel a little guilty as I rip chunks of the sacred cow apart in front of them.
But never mind, if we start worrying about other people's belief's in this time of modern multi-cultural society, we soon won't allow ourselves do anything. Which would be bad... but at least my jaw would stop hurting.
