Jalima1108, I loved your glaucoma story! Something similar happened to me when I was queuing to pay for meat at the butcher’s. I was next in line and since I can’t stand for long periods, I leant against a door frame next to the person who was paying, and explained, rather apologetically, why I needed to come forward before it was my turn. Without even looking at me, the cashier said: “Perfect”. Luckily the customer, who was the person I was apologizing to, smiled at me and said OK.
At least the cashier didn’t go on to ask me what my plans were for this afternoon. Check-out operators seem to be prompted to ask this, since they often do so even while talking over their shoulder to someone else. Sorry, a bit off-topic - nothing in the slightest bit superlative about people having to trot out stock phrases when they’re bored, and I feel for them. Their own plans for the afternoon have to be to repeat such phrases ad infinitum.
