Today I went to my favorite bakery/cafeteria/restaurant/grocery store (yeah it's one place, but not large enough to be considered a supermarket - IDK the correct terminology in English but you get the gist). It's a nice place if a little pricey. About a month ago, they installed a gate. Next to the gate, there's a huge metal thing with a single red button. When you press the button, it tosses an electronic ticket (that stores every purchase you make in the system) and the gate lets you go through. These are not synchronous, sometimes the gate is unlocked a lot sooner than the ticket is tossed. So today, after I got into the store, an employee had to run towards me to give me my electronic ticket. Okay.
I noticed that, despite the machine having only one very big button, lots of people still need to be instructed by the employee in order to enter, and he's constantly manually handing out the tickets. There is also a gate to leave that slows things down.
In this last month, I went a lot less to this place. That's because, whenever passing by, I used to enter just to check things up, see if there was something new or appetizing. You know, impulse buys. The need to check myself in and out (even when I don't purchase anything) made me quit that habit. I think other people are the same. Besides, what's the good of automation if it requires a human being to make it work correctly? AFAIK, the analog system worked. And we're not in a dangerous part of town where one needs to worry about people putting products in their pockets.
That's why I say: sometimes, there is such a thing as too much technology.
