It used to be that our LA had a Teachers' Centre (a former primary) which was used for various training days.
If it was a morning or afternoon, you got a coffee and biscuits. If you were there for the day, you got a rather satisfying old-fashioned type school lunch. (Custard! Yum!)
Eventually, this was all cut back.
By the time I was a HoD/Faculty Head, the lunches were no more. Most training days were cut back to a training morning or afternoon.
We got word that there was a mandatory training day for secondary NQTs - half those in the LA one day; the other half the next.
On the first day, the NQTs discovered that there was no lunch available, but - for some reason - they'd not been informed.
The former school was in a coalmining town currently consisting of nothing but dormitory housing, barbers, nail salons and pubs. The pub across from the former school was open for lunches, so most of the NQTs toddled across the road for lunch.
The next day, the Education Officer in charge of the training day sent a strongly worded email round all secondary schools in the LA - half the NQTs hadn't returned for the afternoon session.
