"Two men in FSB (Federal Security Service) uniforms barged in.... the taller of the two officials, the one with more lettuce on his chest.."
The only my suggestion for "lettuce" here is "hair", but how could one see the chest of someone in the uniform?
When we ask for context and source, we don't just want the title and author of a book. What we want is an answer something like "I am currently reading a book about two policemen who meet when they are trying to solve a murder case. They have just left a bar when one of them says "Oh shoot. I've left my keys. I'll be back in a minute". What I want to know is why the man says "Oh shoot" - is he suggesting that the other policeman should kill someone with his gun?"
If you posted "A man says "Oh shoot". What does that mean?" and we said "Where are you getting this from?", it would be no help if you answered "From Cujo by Stephen King".
Do you now understand why we need context?
Remember - if you don't use correct capitalisation, punctuation and spacing, anything you write will be incorrect.
I agree- I've heard fruit salad to refer to the medals, but never lettuce.
I'm not a teacher, but I write for a living. Please don't ask me about 2nd conditionals, but I'm a safe bet for what reads well in (American) English.
