No Fuel on Numerous occasions and poor service

I prefer using BP to fill up as I earn Avios Points,<br> I live close to these two filling stations, but they are often out of fuel.<br> At least 6 times in the last year.<br> They were both out of fuel today 08/12/2015<br> <br> At Louis Botha - the attendant at least told me. (the service is usually good here)<br> <br> At Ivy Road - no one even bothered to come out to the car and tell me, I waited at least 3 minutes and hooted, but with no luck. Their service is usually poor.<br> <br>
