Unwilling cellphone surfers pump attendees

This morning at 5h30 by Astron R72 I wanted to fill my vehicle with fuel and as I entered I was the only vehicle at the pumps but no attendees were present and most in the room but didn't came out for 5 minutes to help , at this time I was now running late for an appointment so after 5 minutes of waiting I decided to hoot for the pump attendees give up their precious cellphone time but no response then more vehicles came and then they stood up but now they went to the other vehicles that came after me. I'm spending over R8000 a month on fuel by Astron R72 Motors for my business and this well may be the last for this weren't the first time either but the previous incidents I weren't in a hurry but this time I could have lost my contract with my client. Lucky Total garage were more whiling to help after I lost it that they didn't respect me for being first come first served.
