I'd suggest to allow for any snagging problems with post etc (and avoid queues on day) with many fans travelling away from home on holiday or perhaps having to make plans to exchange tiks with family etc or meet others in their group, probably at least a week or two if they really had any thought or consideration ?
Any jobs suitable for you at the club ?
Exactly this. Sending things out this late allows no time for postal problems, errors on the smartcards, mistakes or any of the above. It's not a major issue and not the end of the world but it's common sense to allow a bit of room for manoeuvre. I accept the ticket office has had some upheaval during the close season but these delays and lack of efficiency are hardly out of character.
