A vending machine (directory being models\props\cs_office\vending_machine.mdl) is spawned via either a console command or !cc - and with this vending machine it has the ability to dispense water bottles (by pressing "E" if possible)(models\props\cs_office\water_bottle.mdl). However, this event will only occur for admins flagged 'a' to 'z', anyone else (non-admins) who attempts to use this newly spawned vending machine will explode.
As absurd this idea is, I hope someone could help with such plugin.
