If I say: I've seen him at the supermarket" does this imply I've seen him several times at the supermarket or can I say it if I've seen him only once (without including the word "once")?
In other words does the present perfect always imply several times? Some natives seem to think so.
To me "I've seen him at the supermarket" means I've had the experience of seeing him at the supermarket and it says nothing about how many times I've seen him. So even if it was only once I can use present perfect. Correct?
