I either do this, or mentally divide by 5 (how many 5s make this number?), only caring about the closest whole number - I prefer to tip in whole dollar amounts to make the math easy.
Eg. $39.53 is about $40, 40 is 8 fives, so tip $8
If the service wasn’t great I round down instead of up.

I multiply the tip by 5 to double check my math which is how I know it comes out as a dolllar higher sometimes.
28x5=140
