I have booked a double-glazing salesperson to come tomorrow, mentioned it to a couple of friends and heard some horror stories. One neighbour said not to be alone as she had one who wouldn't leave for four hours.
I didn't take this too seriously at first, thinking it's just a bit of a cliche. However, the company have just confirmed the booking and asked questions such as, "what's your title?" (I don't use one) and "are you the sole owner?". I think they're trying to prevent me closing the appointment with, "I'll have to check with my husband".
Surely they don't still try these techniques, do they??
