Got back from surgery today and wanted to say it was quite easy using my 510 no LED toy both pre & post op.
I had my case for my glasses that I also kept my PV in, and although I didn't blatantly vape, nor did I hide it, I wasn't bother at all which made all that waiting more bearable !
Couple of other patients in post op recovery saw me, but I think they probably thought they were hallucinating or something after the general anesthetic, haha.
Now, if I had brought a mod or was flamboyant about blowing clouds of vapor arrogantly, then I think I would have been approached.
But, luckily that wasn't the case, and all it took was a little mutual respect. Although, being a rather larger than normal guy probably helped a tiny bit.
VapeOn,
Greg
