Seattle signage not very clear!

While waiting for the bus in Seattle on Third near Pine yesterday, I noticed this sign, and wondered what the hell it means!

The top part seem clear - from 6 to 9 in the morning and 3 to 6 in the afternoon buses come here. I'm trying to catch a bus here, so that's a good thing. 

But what's this "EVERYDAY" stuff? I think of the word "everyday" as an adjective, although dictionary.com says it can be a noun (it has three definitions for use as an adjective and one for use as a noun). Synonyms include "workday" and "common". To me, "everyday" means "common". As in, "Today I'm wearing my everyday shoes." 

So is this where the Common bus stops? (The Fancy bus must stop somewhere else.)

Then there's the bottom portion of the sign. Wow. Seattle, are you sure? It's clear that your car will be towed. But when? Apparently, just "all other times". So does that mean you won't be towed from 6 to 9 in the morning and 3 to 6 in the afternoon? (And, is that Every Day? or just the Everyday Days?)

At least they have a phone number you can call if this is confusing. 206-684-5444. (But don't bother - it wasn't helpful.)
