Learn English – When do we use “suppose” and when “let”

Straps are usually made of leather or a synthetic fiber material. Bracelets are usually made of metal. Often the word band will be used to represent either, though.

You are right in that both have a similar meaning, with a small difference; being condescending has a greater emphasis on the superiority of the person.

For example, a friend explaining the meaning of a word to you in a good-natured way, when you feel they should have assumed that you know the meaning yourself would make you feel patronised.

If on the other hand a friend explained the meaning of a word to you, and added "I wouldn't expect someone on your level to know that anyway", that would be incredibly condescending.

In your particular case, condescending would be closest but I wouldn't actually use either word. I would go for something like ungracious, impolite or rude.
