Now you made me run off to google again. For those OCF members like myself who wondered "tuck shop" : Is that some kind of plastic surgeon doc in a box (TV show: Nip & Tuck)? It turns out from Wiki
T[quote]he term "tuck", meaning food, is slang and probably originates from such phrases as "to tuck into a meal". It is also closely related to the Australian English word "tucker", also meaning food. A tuck shop typically sells confectionery finger-food, such as sweets, crisps, soft drinks and so on. In recent years, there have been moves to change to a wider variety of "healthier" foods. In Australia, where the tuck shop will typically be the only source of bought food at the school/club, the menu is more substantial and is more similar to the school dinners provided by the British government.[/quote]
so now I get Klo's joke: it's funny.
