I fly BNE-MEL-BNE fortnightly and at all hours. I haven't been keeping strict records but I think the catering is something like this:
First flight until 1200: Gourmet free-range grain and tropical fruit breakfast delight (pejoratively also known as the muesli bite or 'Oh I couldn't eat a
whole one') with tea, coffee, juice or water
1200-1300 or maybe 1400: High tea-inspired delicate finger sandwiches (you might know it as the unfairly maligned 'wait so it's one sandwich between four of us?' quarter-sandwich) with tea, coffee, juice or spring water
1400-1700: The dreaded Jamz (an abortion of two small biscuits stuck together with some kind of fruit spread that will outlast time itself) or the oatmeal biscuit (same thing but make the biscuits with oatmeal and don't stick them together with jam. Is that an improvement? Hmm hard to say...) and of course your choice of tea, coffee, juice or spring water
1700-1900: Happy Hour! The one good snack of the day! It could be the tasty salt and vinegar chickpea snacks! Or maybe the pretzels and almonds! No matter, the punters love them and they come with soft drink or beer or wine so you're bound to be back for more*^ (*there isn't any more. ^Weekdays only, otherwise it's your choice of tea, coffee, juice or water)
1900 until last flight: Happy Hour is over and the free drinks have been locked away. To make up for the pain of missing out, you'll receive the salt and vinegar chickpea snacks or similar but only with your choice of tea, coffee, juice or water
