Once had a cold caller giving me the big speil about conservatories. We discussed the many options/finishes that I could choose from, etc. We, eventually, agreed a date and time for the installation designer to do a home visit. I told the caller to advise the designer that our lift might not be fixed by the time of the appointment and they'll just have to use the stairs. "Stairs?" he asked. "Yes." I said. "I live in a 5th floor flat"
He hung up. I don't think that was very nice especially as I hadn't spoken to anyone all week.
