The other day I went flying in a Sportstar over YVR. I haven't made that trip for well over a year now and last time was in a '172, not an ultralight, so according the CFI, I 'over asked' for the clearance through the zone. I actually asked specifically for the "Oak Bridge" transit, but instead, I should just have asked for clearance through the zone and let the controller tell me which route to take. The controller made 2 unsolicited calls to me to warn of passing traffic and to clear me from the zone. I was very surprised at the way he announced my call sign - ennunciating each mnemonic slowly, pausing after each word, and loudly as though I was a 10-year-old or something (and taking a lot longer in the communication as a result). For my part, I was clear, brief and accurate in all communications so here's my question:
There are 3 possible reasons I can think of why he was IMO acting strangely with my callsign:
1) He thought "Hmmm, ultralight, must be green, so I'd better make sure he hears me
2) He was angry that I asked for Oak Bridge instead of the more general request for clearance through the zone
3) I may have over-enunciated the "India" part of my callsign (not sure) and perhaps he was mocking me
Anyone able to comment?
