Asked everyone invited to Christmas at ours to do a lateral flow test first as MIL coming and she would like this to happen. DB has kicked off at requirement as late notice and not a legal requirement and thinks I am being unreasonable to ask as not asked for this before. I don’t think it is at all unreasonable as MIL is in late 70s and has taken every precaution so far. Have offered to send a test if he can’t get hold of one if he lets me know asap.
