Giving context to currency exchange
When traveling abroad, sometimes a straight currency exchange doesn't tell the whole story. Your home's tipping and tax-adding customs may differ from where you currently are, and the price tag you see may "feel like" something entirely different.
If you're running this for the first time, note the main UI is a paging scrollview. Scroll! Will add indicators and/or onboarding in the future, or rethink this whole thing.
An example:
In Norway, a beer might cost NOK 96. That price, however, includes any tax, and tipping is not expected in Norway as it is in some other places. As a straight exchange conversion, that could work out to USD $16.00.
In Texas, however, a price on a menu usually has an 8.25% sales tax added to the total, and it is customary to tip 20%. So in reality, that $16.00 beer should "feel like" roughly $12.50, with a dollar in tax and a $2.50 tip.
By cataloging these customs in various locales, I hope to bring some additional context to currency exchange, and make it all a little bit more rational.
