I managed to lose the key card to my complex/building about 10 days ago, so I had been either waiting for people to leave or bothering the guard to let me in. Yesterday (Sunday), I asked the guard to sell me his toggle. While he said "no" at first, an hour later, he told me I could have it for y50 (as long as I remained hush-hush about it; I'm guessing his bosses don't read FT). The official price is probably only y20, but going through the "official process" is certainly worth more than y30.
