"Terrible urgent care and A&E"

my son in law went into A&E with atrocious back pain, they fairly quickly sent him to Urgent Care so that the A&E wait times are lower but the Urgent Care area was packed with people standing and sitting as there weren't enough chairs. He waited for over 4 hours to be told he was next, then a further hour and a half after being told he was next, to be seen. I understand children need to be seen faster but at which point do regular adults get a chance to be seen. I would rather go to Stoke than come back here.
