I have a fixed desk but an absolute clean desk policy, so what I leave behind in the evening has to go into the pedestal.
Only chargers (phone and laptop) and keyboard, mouse and headset can stay.
In the pedestal I have:
pens
notebook
my personal mug
water bottle
some ibuprofen/paracetemol
handcreme
tissues
I do have a stapler and holepunch but I actually can't remember when I used it last as we are also 99% paperfree.
The office has a kitchen with hot and cold water tab for drinks, sink, dishwasher, really nice coffee machine, microwaves, fridge and freezer.
We are getting tea, coffee, fresh milk (dairy and oat) all free.
The kitchen is stocked with mugs, glasses, crockery and cuterly.
Some people have lockers, mainly to store breakfast cereals or several pair of shoes.
If you are cycling, you can have a locker in the basement where also the showers are. One of my colleague has spare clothes, shower items and make up there.
