Gas stations seem to be able to handle it. Why can't we expect the same for charging stations? Build for peak capacity. The chargers don't draw much when they aren't plugged in to cars. If we expect to succeed with charging infrastructure we need to make it convenient, even during holidays.
Contrast Tesla superchargers in CA with, e.g. getting gas at a Costco. They experience similar degrees of queuing. There is a limit to how much of peak capacity you can build for. The solution is not to increase the capacity of a single station, but to build more of them (just as with gas stations). Which is obviously what Tesla is doing.
Building a gas station for peak capacity would mean building so many pumps that you never have to queue. Even when people leave their car by the pump while going to the bathroom or grab a slushie and some snacks.
That is a solved problem in most of the world. I have waited at a gas station at most 5 times in my life and never more than 2-4 minutes. Going to the bathroom or leaving the pump I have never seen anyone do. If I did I would turn off the pump at the big red STOP button as leaving the pump running unattended is illegal.
I think he's saying leaving the pump after getting your gas. That's very common in my area. You pump your gas, go into the shop to get something and you leave your car at the pump. Nobody leaves their car while pumping.
It's not uncommon to have to wait a few minutes for a pump to open up in my local gas station and it's got about 15 pumps.
Where do you live? Everywhere in the US I've been the normal use case if you're getting something other than gas is to start the pump and then walk into the store to get food/use bathroom/etc., while the tank is filling. Yes, it's illegal, but people do it all-the-time.
