spilled drink etiquette

I always will offer to remake a spilled drink for a customer because accidents happen, HOWEVER I feel like people have become more and more demanding when it happens. Like not asking if they can have another but just telling me to make another, expecting a new drink even if theirs was half gone, not giving any details as to what their drink was. It’s very frustrating since I work at an extremely high volume cafe and there is literally never a break in the line so I have to pause my new tickets to do the remake. Again I would of course offer to do all these things it just is annoying that they don’t seem to appreciate it or notice the fact we are extremely busy with orders. Anyone else notice this / what is the procedure to handle spilled drinks in other very high volume cafes?
