Just read a thread on Mumsnet about a lady in a gym who was “told” to move from a piece of equipment by two other members so they could exercise side by side. Similar equipment was free but not in pairs. She refused because she was already part way through her exercise program. One woman became quite angry. However they did not think to ask a male member who was also using a machine that was one of a pair.
Im not a gym goer. However many posters commented that this was poor gym etiquette to interrupt a member who is clearly into the rhythm of their set exercise program. You cannot simply hop on and off pieces of equipment without detriment to your planned workout routine.
Once I have settled myself somewhere (eg train/bus/plane seat) and stowed all my belongings away I will not move just to allow entitled people to sit together. If they want adjoining seats they should come earlier or book them. My usual response is “Im all right where I am thank you” with a decided do not challenge me edge to my voice.
