Last week we received our international calling cards from a major international telecoms company. Included in the pack was an invitation to win a holiday to Hawaii, London or Colorado. I thought I’d enter and completed the entry, wrote out the letter and affixed a stamp. Then, just before sealing the envelope, I read the small print on the back of the competition entry form – ‘entry open to US citizens only’ – I am a UK citizen based just outside London! I thought to myself, what a waste of time. How many other ‘non-US’ citizens have received the same pack as I did and completed the entry form, maybe even sent it off?! The lesson I learned is never to invite entries from people who are not eligible – it only annoys them!
