Can a 85W MagSafe Power Adapter be used with my Macbook Pro 13 (Mid 2012)?

If you use a high-wattage power supply for any laptop, including Macs, that only requires a lower wattage power supply that is in fact better. <snip>

Please explain how using a higher wattage power supply is "... in fact better"?

Yes, you can use it, not an issue— the machine regulates what it needs.

Absolutely! The gentleman at Frys is correct.

FUN FACT! A savvy mac technician will always keep a single Magsafe (1) 85w power supply (along with a MagSafe->Magsafe 2 adapter) with them such that they can safely power various MacBooks made from 2006 onward until the USB-C models were introduced in the past couple/few years.

Interesting you ask the question and you answer the question. 😉

Good computing SlamDunk1978.

It's better strictly in the sense that it produces less wear and stress on the power supply since you are only pulling electricity through the transformer well below its rated capacity. As long as one doesn't mind the larger size/bulk and higher cost, it's better.
