Everything is closed at night between tides. I usually try to bring a snack or slum it at a 24 hour convenient store.
I try to get home and into bed as fast as I can so I don't end up wrapped around a telephone pole or useless the day after. If I have the energy when I get home I'll make myself an omelette and try to time it right so I have one ready for my wife when she gets up. Breakfast in bed usually seems to help negate the fact that I left her alone all night.
