From the post it's clear that the shop has a set schedule of services and prices that the bot is pulling from. All the things you're saying are true for a shop that needs to custom quote each job but do not apply to the situation as presented.
It's clear that the author interpreted the data that way, yes.
And perhaps the shop actually charges the same for brakes whether it is an Ford F150 or a Toyota Corolla.
But that seems very unlikely to me. While they're both very common vehicles, they are also very different and the parts have substantially different costs associated with them.
