I'm surprised at the number of places I shop that take apple pay. Most big box stores accept apple pay. Most supermarkets, most fast food places. Lowes, home depot accept it. As you noted, Whole Foods and Trader Joes as well. The holdout is CVS.
Most businesses today, that accept NFC, accept apple pay. Apple pay is much faster than fishing a credit card out, unless one is holding the credit card in their hand. Apple pay is also faster, imo, for whatever reason than a credit card. I always try apple pay first, because until you try you don't know.
On average I use apple pay about 5-6 times a day in various establishments. Even in the corporate building the cafe accepts apple pay as do all of the vending machines. The vending machines in my gym also accepts apple pay.
