it says thing in title when I try to run this in turtle:

text.input ("Do sir want some drinks?")
variable = read()
if variable = ("yes") then
turtle.drop()
end

What am I f*cking up here?

Lua doesn't expect to see a variable assignment using = there, so it complains at you. == is used for "is equal" comparisons.

now it says "bios:366: [string "turtle"]:2: '=' excepted

text.input ("Do sir want some drinks?")
variable == read()
if variable == ("yes") then
turtle.drop()
end

Take a look at this. If you're still having trouble, post the new version of the code.

To memory, I don't there is a text.input, at least, not unless you pre-defined one somewhere else.

In if statements, it should be

 if variable == "yes" then

so basically, drop the parenthesis on the if statement.

print("Do sir want some drinks?")
variable = read()
if variable == ("yes") then
turtle.drop()
end

This should work. If you want to display text, use print/write/term.write
When setting a value, you need only one =
When checking if two values are the same, you need two =
