I pre-paid for the parking. Upon arrival, we went through the barrier and parked. Noticed that the numberplate was not printed on the ticket. There were no signs telling you what to do in this case. Luckily a van with a parking warden drove past and we flagged it down. The chap was helpful and told us what to do, however he did mention that the ANPR cameras are very intermittent. These obviously need to be replaced with more reliable items, but also there needs to be some sign-age on what to do in the case where it hasn't worked. Also the tarmac is way passed its best and very uneven. There where also a good number of vehicles in the row we parked in (between 10 and 11) that were parked very badly, effectively taking two spaces.
