Hi Penny, not heard anything about this yet, however I can tell you what happened last time they trialed this about 10 years ago
It was a bit of a disaster, and dropped after about 6 months, however they forgot to tell the trial stores that the trial had ended and also forgot to add the hours back into the stores wage budget.
From what I remember the PFS was meant to be single manned from open till 09.00/10.00am then 18.00/19.00 till close(22.00). We had a couple of stores in our group trialling it and they had slightly different times.
They introduced magnetic locks on all doors, that can be un/locked from the till area.
Only a set amount of customers were allowed in at a time, and first and last thing customers were served through the hatch.
When single manned there was 4 pay at pumps only and 4 pay at kiosk pumps open.
There was a direct link to security support via cctv and intercom for any emergencies.
Obviously any issues on the forecourt, Duty manager had to be contacted to send someone over as the single colleague couldn’t leave the kiosk.
They were not allowed to fill or do any stock control routines,(they were meant to be completed when double manned)if they needed a toilet break they had to contact duty manager.
Like now duty manager had to open and close with the single colleague.
I know the PFS managers didn’t like it, and tried everything to keep it double manned even when they were meant to be single manned.
Then instead of rolling out the single manning in PFS, they decided to start getting rid of the PFS managers shortly after.
Personally I cannot see any reason why it couldn’t work being singled manned.
If you look at most other companies PFS kiosks they manage perfectly fine being single manned without having a main store to support if anything happens.
Many of these companies pfs kiosks are in remote locations and 24 hours.
