It seems so.
Thank you both so muchI don't think I've heard any BrE speaker say that as a response to 'thank you'. It sounds like an AmE expression only. I'd only use 'sure thing' to mean 'certainty' ('It is a sure thing that the sun will rise again tomorrow'.) In AmE it is also used to mean 'certainly' (as a response to a request) ('Can you pick up a loaf of bread later?' 'Sure thing.')
Thank you again so much!It's just a casual alternative you might say to someone.
I think it's something like my help is a sure thing that this means that I certainly help whenever you want, right?To say that the favor done is small and undeserving of a formal exchange of pleasantries. There are many informal expressions like "Sure thing."
As pointed out above, it is a very informal alternative to "You're welcome."Why is "sure thing" used instead of "you are welcome", please?
This sounds like a reasonable theory about what Sure thing means, taraa. The speakers who use sure thing or no problem probably haven't given much thought to their replies and what they might mean. Like Language Hound, I don't much like those replies. To me, they are a little too casual and dismissive to be appropriate replies to a courteous expression of thanks.I think it's something like my help is a sure thing that this means that I certainly help whenever you want, right?
