I invited 2 friends to YMCA for sauna, I am a member, they are guests, am I expected to pay for them?

You pay because you invited. If I didn't want to pay for them, I would have offered that option but then added that they needed to pay a $4 fee. This way they could decline and not think you were paying for them.

If you invited them, it's your treat. It's the same as inviting someone to lunch-- you would be expected to pay. You're lucky that $4 each isn't terribly expensive. Next time, handle it this way: "Hey, I'm a member of the 'Y', and I can invite a guest to use the sauna. It'll cost $4. Would you be interested in coming?"

It depends on the wording. If you say, "I'd love to take you to the sauna to relax!" then that implies you're paying. If you ask, "Would you like to meet me at the Y one day? You'd only need to pay $4 for a guest pass." then obviously they will be paying. In this situation, I would pay. Next time be a little more clear that this is just a get together, not something you're hosting.

You invited, so you are required to pay. Inviting someone makes you the host, and a host always pays for their guests. And holy cow, it was only $8! It isn't like you were expected to pay for their dinners and hotel rooms!

If you offered the invitation and expect your friends to come then you should pay, but if your friends invited themselves they should pay.

It is like a BBQ, if you invite people over, you pay for the food. If the neighbourhood is holding the BBQ at your place, they should bring their own food.

If you invited them then you pay- Sorry.

You invited them, you have to pay.

I agree with you. If one of my friends had invited me, I would not think twice about paying my way.

unless you had previously discused the payment issue (Dutch Treat, pay your own way ) than it would definatly be your treat to your friends

I believe that if you are hosting them it is your responsibility!

Whats $8.00

Good company don't come cheap!
