I was trained to do this. From day one of dedicated 8-hour training sessions, we're trained to find customers the right "solution" rather than get the most money. This requires using the APPLE technique (acronym, google it). The second P stands for "Present a solution for the customer to take home today." It was common knowledge at the time (4 years ago) that consumers were brainwashed to thinking faster/more is always better. But when we can save them hundreds of dollars, this isn't the case. There were many many times I talked someone out of a $2,000 MacBook Pro for a $1200 entry-level iMac with double the specs because after probing (the first "P") I learned they didn't need to be mobile. This was really, really common.
And note, this isn't about trying to convince people to spend less. Sometimes after probing, we learned they needed _more_. It is about the RIGHT solution.
To add to this: specialists don't earn commission. We weren't ranked based on financial sales numbers (there are other metrics, however). There is no incentive for specialists to sell more expensive or less expensive things. It is about the right thing.
So, this guy was just doing what he was trained to do. It is Apple store standard.
