Square Inch Anthropology

Considering the message's medium, this is assurance for tourists who are wary from prior experiences with the "locally calibrated" orange juice suited for Thai tastes. All knowledge has a price associated with its acquisition, and I'm interested what that process for this juice stand owner; was such knowledge acquired passively through watching the wincing faces of non-locals as they experienced the disconnect between their expectations of how orange juice "should" taste based upon past experience (sweet) versus the present experience (salty)? Or was such knowledge acquired more actively, or perhaps even forced upon the owner by a non-local (or perhaps several over the course of time) voicing their dissatisfaction with the orange juice and/or demanding a refund?

A sampling of what some might consider "interesting" candy flavors. Dispensed on a domestic airline flight, what could have influenced the airline to decide that these were the ideal snack to give out on a flight? 

Out of the dozen or so flavors (including more conventional ones such as the predictable line-up of fruits; cherry, watermelon, grape, etc.), can the origin of these "extraordinary" flavors be generalized about? Does an "Iced" lemon taste different from a "Room Temperature" lemon (and judging by the presence of ice cubes on the wrapper, "iced" in this case likely does not mean "having had icing/frosting applied to it")? Though butter is included in dishes here, how high is the average person on the street's knowledge of what a stick of butter looks like? Probably not high, which is perhaps why one only sees this on an airplane flight - air travel remains out of reach for most people here.

Also, all four wrappers bear one attribute in common: their depiction of two miniature candy wrappers in the lower left corner. Does logic lurk behind this seemingly gratuitous graphical flourish?
