This might be a stupid question, and I'll accept the flames if it is.

I flew the last ORD-AUS out of ORD last night in F, and I'm used to getting a "snack" on this route, as it's a nearly 3-hour flight. The FA came around with drinks, and then a little platter filled with mini-bags of Tostitos and sesame "party mix."

Was it simply that we left so late (flight departed around 9pm,) or should I grab a sandwich before I get on a flight in F from now on?
