While on the line I could never figure out where the ashtrays went, true, some are removed by the turnaround cleaners, who rather than empty out the ashtray, found it less time consuming to simply remove the ashtray from its socket and disguarg of the whole thing. Last year my wonder at the ashtray mystery was no more, I noticed, while on the beaches of Gran Canaria, that alot of people were bringng them with them and planting them in the sand, to use during their holidays!!
