Don't forget a trunk camera in case someone gets in there to prank you. And a backseat camera because the seat I'm in makes a blindspot when I turn around to yell at the kids I ran over before to shut the hell up or I will turn this car around and not go to the hospital, so help me god, Aiden. And one in the glove box so I can make sure I didn't lose the owner's manual so I know how to switch between all these damn cameras.
Only experience I have with them is one my mom got around 2008. Pretty quickly developed issues with the charging port. Returned it and have avoided Acer products ever since.
Where I work now, we have a regular customer who is like that but with oil and vinegar. We have a single bottle that the oil and vinegar go in, which we shake before squirting it on the sandwich because, you know, the two famously don't like to mix. There's a very fine tip on it of course, and normally a sandwich gets a few passes back and forth for coverage.
It took a little while to find where the line for enough was with the customer, but eventually I worked out that just unscrewing the cap, which leaves about a finger sized opening, and dumping that across the sandwich top and bottom, with a little overrun on the sides, finally stopped the requests for more. I still give him an extra side cup just in case. That dude just loves him a soggy, oily and vinegar-y mess of a sub.
That's fine, but once it's past the limit, do NOT attempt to flush it away. It will be very mad at you for turning it into a wet claw tornado.
