Thankfully I would have nothing to report..... I've had a few near "misses" though:
The most frustrating and annoying day ever was 25th February 2014 when conditions on 2m were dire. The weather wasn't any better. On both Tinto GM/SS-064 and Dungavel Hill GM/SS-165 I spent so long trying to qualify the summit on 2m SSB that I had to add a couple of HF contacts to the log using Paul G4MD's set up.
Other "difficult" days were -
5th April 2006, Houseden Hill G/SB-010, back in the days when I was only running 2m SSB. I made one contact and then had to bungie the beam to the mast and use 2m FM to raise the guys up in Edinburgh. The summit was qualified with the assistance of Ally 2M0PMR who rallied the local troops.
23rd May 2009, Gamallt GW/NW-065 - another 2m SSB activation from a screened summit. I managed two contacts in quick succession and then nothing for an hour. Thankfully it was another joint activation, so I crossed to Paul's position and requested that he ask one of his chasers to spot me. John GW4BVE did so and I managed another 4 contacts including John.
14th November 2010 Nine Standards Rigg G/NP-018 - despite being on charge for well over 24 hours, the 12A SLAB I was using expired as soon as I went to transmit. It was a bizarre occurrence really, as I had LiPOs in the car and was only using the SLAB so that I had enough battery power for the next couple of days as a total of six summits were planned. I now take my charging kit with me on all outings where an overnight stay is involved. NP-018 was qualified using my 1W handheld.
As for broken antennas, I did once have to use the aluminium foil my lunch was wrapped in to mend the dipole on the 2m beam, using a stick and a couple of tie wraps to splint the joint. I worked well for 3 activations.
.....and as for summit references, yes I have had to ask several times. Much more common is someone calling in for the WAB square - usually I haven't got a clue!
