So I use the wonder wand and towel dry myself most washes. Can we talk wonder wand car wash etiquette? The one I use has the vacuums before the wash which is a stupid setup. Say you are the 3rd car. One in, one behind at vacuums, then you. If you are still vacuuming, shouldn't you offer the guy behind to jump in since the bay is open? I think so, but it never happens. There prob isn't room to squeeze in, but you could drive around and back in. I'm also of the opinion that taking your time at these types of washes is a dick move. I'm in and out in a few minutes. You are literally spraying your car, it shouldn't take long and it won't get much cleaner the more you spray.
