Even the most experienced traveler gets stressed out about a lot of things at the airport: boarding times, your luggage's weight, TSA scanners, and the classic worry of going to the wrong gate for your flight.

Sensible employees are burdened by sensible choices. It's the compulsory reaction of the working class to choose an affordable option versus an expensive one, so when a traveling salesman is faced with a frugal travel choice and a lavish one, they're most likely to pick the cheaper option. However, because company policy isn't always so practical, sometimes the rule-following beancounters come after you for the most reasonable of choices.
