Yes, I noticed this too - I thought all the names were in the same size font, but it'd appear not, as "DAVID" appears to be much larger than "ADRIAN"... I thought it was due to the number of letters in their names and how much they can fit onto a badge, but there seems to be a huge border around "ADRIAN".

I'd have thought if it was a printing error, it'd have been corrected and re-printed... although I think they print many name badges for each person, so maybe they couldn't be bothered to correct it.
