LETTER: Here's a tip: don't be greedy!
At the Esso petrol station in Langney, Eastbourne, this morning I personally filled the tank with very expensive fuel (Â£1.26 / litre).
When given the credit card machine I saw added a suggested gratuity of £0.25.
As no service had been provided I did not feel obliged to comply so I asked for this not be included. Is there no limit to the greed of oil companies and their agents ?
