visiting the tower and take them around their control zone for good relationship is worthwhile.
There is another possibility to get a landing clearance- but you have to be careful with the wording so...
A fellow pilot, I was Copilot at that flight, said „I am low on fuel“
He got his clearance to enter and to land and a special greeting committee with fancy lights on their cars 🤪
The whole fire brigade awaited us.
Should have said „Minimum Fuel“ and everything would have been fine 😏
