Speaking on the BBC, Stephen Fitzpatrick, Founder and Chief Executive Officer of the firm, said: “I would like to start by apologising again. It is, unfortunately, the case that we are a large company and somebody had a bad day, they sent out an email and we should have caught it.
“It is an email that never should have been written.”
The mail said: “Ginger keeps you warm by encouraging blood flow, but beware of chilli as it makes you sweat, so you will feel cooler.”
Mr Fitzpatrick added: “I think it was probably meant with good intentions but this is the kind of email that causes a lot of upset. Nobody takes the situation facing British customers more seriously than I do so it is really upsetting and embarrassing.”
