Tengah Tower in the late 60s also had a Locally Employed Person in the shape of young Frank Goh, a Chinese in his early 20s. Frank would make the brews, pop down to the Coke machine in the entrance lobby [20c bottle, IIRC] for you, and did the general cleaning. Fond memories of Frank - jolly good chap all round.
In a normal Tower, it was of course the lot of the AATCs to make the brews, as the ATCOs were usually chained to their consoles by a headset cable. However, in a 'nice' Tower, you did occasionally find that a slack/spare ATCO will do the job, especially if the AATCs are particularly busy. And as SATCO Waddington, one of my self-appointed "War Roles" on callouts was to fill and switch on the water boiler, so that the crew could have a brew once they'd done all the essential tasks [at whatever ghastly hour the sirens had gone off!].
