On the option of the meeting place: Does it terminate by going to the restroom, even if it is in the same location?

The questioner : We have established in the past that if two parties, for example, transact in a piece of land and are in the meeting place, and one of them gets up to go to the restroom, then the option is considered the option of the meeting place and it terminates. However, if they are on an airplane and the duration is long, the option of the meeting place does not terminate. But it is said, for example, regarding the restroom on the airplane: if one of them enters the restroom on the airplane, would that not be a termination?

The Shaykh : Yes, just like the restroom in the house.
