What does ser un hombre de costumbres mean?
Expression
to be a creature of habit
A defence rather than a description: it is said about yourself, always after somebody has pointed the routine out. It carries a note of mock pride. There is also ser de costumbres fijas, which is neutral, and ser un rutinario, which is genuinely critical.
Desayuno lo mismo desde hace veinte años. Soy un hombre de costumbres.
