Pissing Me Off This Day

Went to book a Tesco Home Delivery for the morning and found that they had already put up their Xmas delivery slots and not thought to tell me! Last year they emailed me in advance. All the slots for Xmas delivery have already been booked but I managed to get one of the last ones for the 23rd...better than nothing but it annoys me that I can't get one for Xmas day itself.
