reply early hours sunday saying thanks just got your text
Seriously though, when I worked for Reg Vardy, the security guard regularly took messages from people who phoned at 1 or 2 in the morning.
Whilst the majority were drunks trying to be funny, the others were genuine and did become sales or service customers. The sales guys were always ready to give the messages a go as it was easy to find the genuine enquiries. Many of these genuine callers were shift workers and had seen an advert whilst on a break, albeit in the middle of the night.
