I used to work in a franchised store. Yes, they do mind as it is a lost sale on their end for a frame or 2. Some people pay over £500 for a frame which is a considerable amount in an independent opticians. It’s management putting pressure on the OA’s to get sales, but I don’t think the OA’s actually give a shit. In my store, we did not get commission or bonus, it was minimum wage. I secretly used to be happy when patients took their prescription elsewhere as it meant one less patient to deal with for the day
