Over here in the UK the fuel company BP rebranded itself and started to sell food and other groceries as well as petrol in its 'Wild Bean Cafe'. They now have an in store environment that is air conditioned and smells 24/7 like roast coffee beans. For me that transports me back in a flash to the 7-11 on the 192 on way to or from the parks. It's even better if it's during our summer time and I'm wearing shorts.
On the recently mentioned topic of sounds causing memory recall, when I playback our holiday DVD there is a bird call made by a bird with dark shimmery plummage that looks like a cross between a small crow and a starling, like the US version of a magpie. That noise takes me back to Epcot where they were numerous and quite brave begging for scraps.
