At work we have a target of aiming for 20% usage on Loyalty cards whenever we're on the tills. I did better than I expected, my usage was 28%.
My coworker printed out our results for the day and apparently out of the 3 of us who were on the tills today I've been the only one actively asking if people had Loyalty cards, and managed to sign up 3 who didn't but wanted one.
The other two's results were pretty bad. One of them who is always on the tills when she's in had 280 transactions throughout the day and only managed 7 Loyalty transactions.
We also had some newbie from HR join us for a few hours for what is essentially training. I didn't realise she was new though, so I shyed away from talking to her in case I put my foot in it. I must've seemed quite rude and I feel bad for it.
