Does anyone claim for food eaten when your at work 
Oh no! We've been here before on this subject.
You can't claim on what is normal everyday expenditure ie food and drink.
Now, if you vehicle broke down 100 miles from home and you had to stay somewhere over night (away from home) that would be different.
Within limits even sole traders can take 'customers/potential customers' (!) out for entertainment ie a 5 course meal. Read into that what you will
