I?m 33 weeks pregnant and had an obstetric consultant appointment yesterday afternoon. The antenatal clinic waiting room was packed and there were quite a few women standing up as there weren?t enough chairs. I had been waiting for over an hour as the consultant was running behind schedule and was sitting in the specially wide, reinforced bariatric chair as that was the only one available. A lady came in who was clearly very obese, looked around and saw me sitting in the bariatric chair and came over to stand beside me. Was AIBU not to spring up and offer her the chair? I would have done if there had been any other seats free for me to move to. I did feel a bit bad about it afterwards but TBH I'd been waiting to sit down for ages and felt that she could wait like everyone else.
