Im assuming all the chargers you’ve handled are pretty new and/or well cared for. Do you have any safety concerns at this time with the charging cables or stations themselves?
I've been handling the chargers for about 5 years (this Tesla is my second electric car). The Tesla installed superchargers are always in good shape and well maintained. Sometimes a stall will be out of order but that's indicated on the car computer screen. If you try to use that charger the charge port on the car will flash red instead of green. Sometimes there will be a line to wait to charge. Again, you'll know before you get there as the computer will tell you it's currently full. I've very rarely had to wait but it does happen sometimes.
The destination chargers can be more hit or miss. Those are usually installed on their own breaker box somewhere near the chargers and the employees at the hotel/restaurant never know anything about it. I've turned on and reset breakers myself at destination chargers many times. The bigger issue is regular gas cars (ICE cars) parking in the spot and blocking access to the charger at a hotel all night. The cords are usually long enough I can work my way in and make it work but sometimes I've been completed screwed by a vehicle blocking access. Now a days I call ahead to the hotel and ask them if the charger is working and if it's accessible currently.
Public chargers can be even more interesting. The ones in downtown Baton Rouge are definitely getting a little wore out and ragged. They likely don't have as many safety features as a Tesla branded charger. I plugged into a a public charger in downtown Biloxi once and it nearly fried the car as all kinds of errors popped up and the car went into a reset. So obviously I avoid that one from now on and in general I'll avoid the public chargers as I rarely need them with my Model S.
The Superchargers are your best best for safety and reliability. The destination chargers are usually OK but you should call ahead first if you really need the charger to continue your trip.
