Cultural Tip
In French, 'merci de' is the standard way to thank someone for an action, while 'merci pour' is used with nouns (e.g., 'merci pour le cadeau'). The contracted form 'd'' appears before a vowel or mute h, so 'de' becomes 'd'' in 'd'avoir'. Using the past infinitive (avoir + past participle) signals that the waiting is already finished, which sounds more natural than the present infinitive 'merci d'attendre' unless you are thanking someone while they are still waiting.
