My husbands niece gave birth and we wanted to come in and check on her and we were not allowed, the nurse was so not helpful claiming that this is not a priority and that she has other deliveries to deal with, all what I had asked her is to go in quickly to check on my husbands niece. Very bad service and vet rude with no way of talking back and forth to her. She just wanted to be rude and talk telling me to leave.
