Now that you do it yourself if you mis scan organic tomatoes as regular tomatoes you are freaking going to jail.
Ok exaggerating a bit, but having shoplifting in your record can be life changing, specially for immigrants
No such privilege is granted to regular customers. Instead, the self-checkout station locks itself up, and the customer has to wait several minutes for the assigned employee (who, most of the time, is also working two other tasks at the store) to show up, analyze the situation, enter service mode, and do the undo steps.
My experience is that the assigned employee is always looking for something to do, because he can't leave the self-checkout area, but there isn't anything to actually do there. And well, the store better not accuse honest customers of anything, or else some stuff they really won't like will happen (and that applies to poor customers too).
Anyway, the experience is still so bad that I tend not to use it. But that's because the machines really suck.
I greatly prefer the single queue in self checkouts rather than betting on which cash register line will get stuck on someone that has a pricing issue or something. Obviously, this has nothing to do with self checkouts, but I find single queues far more ubiquitous after self checkouts came around than before.
For lots of stuff, a cashier is probably quicker. But I almost never have lots of stuff.
It's a classic false-positive problem. Most times when the self-checkout clerk has to give you attention, the problem is stupidly innocuous, so they blindly approve, as they have been trained by the system that it isn't a real problem.
I'm sure plenty of things get by them this way.
If this happens, it’s a problem with the judicial system, not self checkouts. I highly doubt it has ever happened, though.
Doing it yourself? Good luck! Hope you've got good service on your phone where ever you happen to be when things go wrong.
90% of travel is probably happening where mobile networks are available. Also, since most travel seems to happen without travel agents today, it appears that "luck" is not that necessary, otherwise people wouldn't be choosing to forego travel agents.
Travel agents were not outlawed. Most people just prefer to save money and do the work themselves (for most trips) rather than pay a travel agent.
Yes, but they're already one level up, so they can fix the problems in their company's immediate system, and then unlike the customer, they're a trusted party in the network of all other parties, so they can mail/call other parties directly and get people there to fix issues without too much delay.
And you can enjoy overpaying for a lower quality vacation if your travel agent is unscrupulous and getting kickbacks from vendors.
That is the actual optimization that happened, I can do more research and communicate directly with vendors.
Those that don’t want to are still free to pay extra for a travel agent.
And you can enjoy all the risk and liability for mistakes made along the way, too, which is where the actual optimization happened in the economy.
