Does this seem out of the ordinary or am I upset over nothing?

Sounds kind of like BS to me, and I have a reason for that:

They charged you for two separate carts. If you and your buddy had just played without the gf baggage, it would have been just two 18-hole cart fees apparently...which you were okay with.

Since your gf rode, they charged you extra? Why?

Well, if it were a third player, you could understand that perhaps you're driving the cart a LITTLE more (back and forth to the ball) and driving more on the fairways which could require more maintenance (on top of the extra greens fees for the divots/putting/etc wear and tear).

But, your gf is just going to your ball every time. NO extra mileage. So why charge the extra $? Because of the extra 140#?? What if I have a big staff bag. You gonna charge me more for the extra weight?? Maybe they'll start charging you extra for bringing your own balls (like a corking fee for bringing your own wine to a restaurant) or carrying more than 20 tees in your bag.

Honestly, whether it's customary or not, it sounds like BS. They charged it because they knew you'd pay it.
