Cultural Tip
In most Spanish‑speaking countries the word 'cheque' is standard, but in some regions (e.g., Mexico) people may also say 'cheque' or simply 'cheque bancario'. 'Porfa' is strictly informal; in a formal email or when speaking with a bank clerk you should use 'por favor' and a more courteous verb form such as 'firmaría' or 'por favor, firme'.
