And of course that's the only motivations possible for a pastoral gift, right?

Two different perspectives here on gift-giving to your pastors.  Perhaps one or both of them will prove to be helpful.  Personally, I don't expect gifts.  I have been blessed with congregations who more than adequately provide for my and my family's needs.  For me, this brief guide is the most helpful.  I can truly think of nothing that would please, excite, challenge, and otherwise make me apoplectic with joy than a congregation full of committed, excited, present, growing Christians.

Other congregations are barely able to pay their pastors a living wage, however.  Some aren't able to even do that.  Their pastors serve faithfully, and accepted their Call knowing that they would not be paid enough to live on.  Their wives work.  They work other jobs on the side to help make up the financial shortfall.  They labor to be faithful.  For these men (or any church worker in a similar situation), the holidays may be a time when some of that hardship is eased through gift-giving.   In which case this guide might be helpful.  

This second guide is frank and candid.  Some people may find it tacky that a pastor (or anyone) would have the audacity to talk about the sorts of things they don't want as well as what they do want.  I'm pretty sure it wasn't written (and I certainly didn't link to it!) to be offensive, but rather helpful for folks who may want to give a gift but are stumped as to what would be most appreciated.  And of course you have to know your pastor/church worker somewhat to know what would be most helpful and appreciated.  The gifts listed here are nice perks and extras.  If your pastor is struggling to make ends meet (and a congregation should know whether or not they are paying their pastor an appropriate salary or not.  Whether the pastor is able or willing to live appropriately on that salary is an entirely different issue!), then gift cards to the grocery store or general stores like Target or Walmart may be more greatly appreciated than a weekend escape.
