"A bad encounter in the Radiology Department"

I stepped into the Radiology Department in Bentley Health Service for the first time this morning after a wrong turn into another department. I was still feeling lost and about to approach the counter but was loudly interrupted by someone saying I need to queue up and that what I was doing was jumping the queue. I was taken aback and then only I saw the 'please queue' at another entrance. Feeling embarrassed, I did not say anything but went to the queue quietly. There was someone in the queue who was served in no time as there were many staff at the counter. I felt embarrassed as they were loud and the atmosphere was quiet and patients waiting all heard it loud and clear. I genuinely did not see the queue and have always waited for my turn in any event. I believe the staff could have given a greeting and directed me to the queue politely. The rest of my experience was better as I was later served by a soft-spoken receptionist and friendly radiologist.
