Wow what a sight. That is amazing. The Apple Stores here in California (near Los Angeles) usually have a 50+ line before they open and are wall to wall with people.
I definitely agree there are bad Apple Stores. The one near our house is and always has been amazing, absolutely amazing. You walk in, someone greets you, you're handled. The store closer to Los Angeles (about an hour away from our house) --- 30% of the employees were talking among themselves and even playing with the equipment, even taking pictures/videos of themselves. I spent OVER 1.5 hours waiting to be seen for my appointment. I was livid, so were many people waiting with me. The "genius" that saw us was impatient, very rude, and dismissive even when his own iPad said our phone was defective, he refused to do anything about it. They were the ones that destroyed my wife's iPhone putting a battery in it.
The Apple Store near our house? We made an appointment and walked out with an apology, a thanks for being AppleCare+ purchasers, and a replacement phone in LESS than 6 minutes after the appointment started. This Apple Store I've gone to for the last 4+ years. Love it.
