It's what we were told in training. The taxi was 'last resort' as services were deemed to be frequent enough. I'm sure there was also a rule of if a taxi was arranged then the people waiting were not allowed to use any other passing service and had to wait for the arranged taxi. I may still have the booklet somewhere with all the rules in but unsure. It may also have been updated since I did my induction.

I don't know what taxi company they used and never once had to call SDC and ask for one.
