Bleh. Bad timing. Sometimes it all works out, and sometimes it’s Murphy’s law all-around.
When you said you got Peets in Seattle, I sort of did a double-take before realizing this was a location inside Sea-Tac. The only other one in Seattle proper (I had to look this up) is actually the dreaded Capital One Café in South Lake Union selling Peets as a branded (or co-branded) outlet.
The general first rule in Seattle is you don’t drink Starbucks in Seattle,
unless you’re hosting out-of-towners… or it’s 3am, you’re next to a 24-hour drive-thru location, and you need some bean in your bloodstream.
The one bit which did surprise me to read was your description of Seattle city tap water. In general, I actually
like Seattle city water — even if it has that aforementioned taste-colour of green (like a transparent-darker green). When I travel back and forth between here and there, I always remember to fill a Nalgene bottle of water (in checked baggage, since our airport here is in the next municipality) so that I can compare waters when I get into town (and vice-versa). It’s always trippy to taste one whilst standing in the other town.
On a merciful upside: at least your visit with family is over.
