I really don't get people who call people on official business on a public holiday. I totally get it if you're calling the family doctor or the neighborhood restaurant or a beauty salon for a spa booking any time of the day, but I don't get it when strangers (who gets my number from various sources) call me up on a public holiday and asks me if my organization can assist them with certain activities or provide official sponsorships etc. I'm like, "gosh if you really want me to help you, please at least send me an official email or contact me on official hours instead of calling me on my mobile on a public holiday / weekend at odd hours like 8pm with a less than politely-appealing tone and manner"
Common sense people. Do not bother your clients, business associates and management of companies whom you are appealing for help, especially when they owe you nothing. Then you wonder why they don't respond to you. if you need the help, you play the rules by their terms. Or at least learn proper acceptable business etiquette.
Come on, personal time is personal time. Holidays are holidays. I'm not a doctor on-call 24-hours. Unless it's a mater of life and death or you're paying my salary, please spare me the drama.
