I don't know. I'm not sure how she actually knows her, but clearly has known her some time. The yellow labels are so excessive to the point of being greedy. My relative showed me the message she sent Helen, she was polite, mentioned she worked for Morrisons asked which store she shopped at because they consistently appear to over stock for so many yellow labels to be available on a regular basis, particularly on meat and fish produce. It showed the message had been seen and a few days later Helen blocked her. It seems odd that she would block someone for asking a genuine question, but even more odd why not block them straight away, why wait?
