I had a book study in my home in the mid-1990's. My living room was very large; we had about 22 or 23 in attendance and plenty of room for at least 12 or 15 cars. We would clean the house and set up the chairs the night before.
People would show up 40 or 45 minutes early. I was usually in the shower at that time. (One time an elderly sister arrived even earlier than that. I didn't even know she was in the house, and I came out of the shower naked and started walking to my bedroom to get dressed. Normally I would lock the door until I was dressed and ready for people to start walking in but I guess this time I had forgotten. ) Instead of pulling their cars in to allow others to pull in behind them, the early ones would park so that no one else could get in. Latecomers would park blocking neighbors' driveways; we'd often have neighbors coming and ringing the doorbell during the study asking people to move their cars. I would always turn off the ringers on all the phones so we wouldn't be interrupted. Some people started bringing their newly-interested Bible students with all their kids. We'd keep discovering that items were missing from the house, and things would get broken. Things like faucets, light switches, and doorknobs. The conductor always wanted the heat and air conditioning at extreme temperatures, resulting in higher electric bills. After the meeting, if it wasn't goodie night (which lasted till after 11PM) the conductor wanted everyone to stay and rehearse field service presentations or demonstrations for the upcoming service meeting.
The group also met at my house for Saturday field service. After field service they all wanted to come inside again, to use the bathroom and the phone. Eventually I told the elders it had become burdensome and was taking time away from my personal study and family study. So the group was moved elsewhere "temporarily".
