Can't offer you any help on Quassy, but SFNE is seldom bad on weekdays. Just try to head to Bizarro or Wicked Cyclone ASAP; unless you're hitting the waterpark, however, you can easily hit everything of note within a few hours. As for Lake Compounce, Boulder Dash will have a line for the entire day, but again, you can generally do everything within a few hours.
Hey, Firestone, thanks for not doing the repair that I went in for, substituting it with a more expensive repair that I didn't ask for, trying to upsell me a ton of expensive **** (that I didn't accept), and doing such a bad job that the car became unsafe to drive and I had to tow it to my regular mechanic's to get them to clean up your mess. If you don't revoke the charges on the card, I'm calling corporate and going out of my way to be such a pain that they wipe the charges just to shut me up.
