Doc..... got three pionts to make.....
1) Its Safeways not Tescos
2) As the Airfield had only just opened again due to water logging, and up until then had not recieved many visitors, I think the Bar/Bistro in question, did not expect orders for all day breakfasts, (Although mine was great, and with 2 eggs) also, the young lady who looks after you is normally unable to run to the shops if she runs out of something as the pilots are often busy with students, and can not hold the fort for her until she returns, although during the summer months extra staff are hired to help.
3) If you want greasy spoon prices, go to a greasy spoon.
